Screening of chiral Diels-Alder catalysts by mass spectrometric monitoring of the retro reaction
Full text linkA rapid screening procedure for the identification of chiral Diels-Alder catalysts by ESI MS
was developed. Screening of the retro reaction made it possible to indirectly determine the
catalyst’s enantioselectivity for the forward, product-forming reaction.
We were able to monitor positively charged catalytic intermediates for the retro-Diels-Alder
reaction. Use of mass-labelled quasienantiomers allowed the intermediates A and B to be
distinguished by mass spectrometry. The ratio of the mass peaks of A and B reflected the
catalyst’s intrinsic enantioselectivity. It was crucial to evaluate the influence of the mass
labels on the reactivity of the two quasienantiomers. Sufficiently strong binding between the
substrates and the metal catalyst was necessary to allow detection.
The method was used for the screening of bis(oxazoline), phosphinooxazoline and bis(imine)
ligands in the copper-catalysed retro-Diels-Alder reaction to identify highly selective ligands.
The selectivities were confirmed by product analysis (HPLC). In accordance to the principle
of microscopic reversibility the ratios observed for the retro-Diels-Alder reaction correlated
with those obtained for the preparative forward-Diels-Alder reaction.
The method was extended to organocatalytic retro-Diels-Alder reactions. Monitoring masslabelled
iminium ions C and D allowed direct determination of the catalyst’s intrinsic
enantioselectivity. This versatile method allowed not only rapid screening of imidazolidinone
and proline-based organocatalysts but also of oligopeptide-catalysts. The results obtained by
ESI MS were confirmed by preparative reactions.
After establishing a reliable protocol for the screening of organocatalysts, the procedure was
successfully applied to multi-catalyst screening. The catalytic intermediates originate from
different organocatalysts with different masses allowing facile assignment of the catalytic
intermediates. After optimising the conditions, multi-catalyst screening showed excellent
correlation with the single catalyst screening

Paratype material. UWA 21332 (internal pygidium), UWA 21333 (internal pygidium), UWA 21334 (internal cephalon), UWA 21335 (internal pygidium). Locality. Western Australia, upper Wandagee Series, Helicoprion-Paragastrioceras Zone (Teichert 1944). Diagnosis. See Teichert (1944: 458-460). Remarks. Ditomopyge meridionalis is the only species of trilobite known from either the Carboniferous or Permian in Western Australia. Ditomopyge meridionalis is Artinskian (Early Permian) in age (Teichert 1944), and is the youngest known trilobite species from Australia.Published as part of Vanderlaan, Tegan A. & Ebach, Malte C., 2015, A review of the Carboniferous and Permian trilobites of Australia, pp. 1-56 in Zootaxa 3926 (1) on page 31, DOI: 10.11646/zootaxa.3926.1.1, http://zenodo.org/record/28800
Shevyrevites Teichert & Kummel 1973
No full textGenus Shevyrevites Teichert & Kummel in Teichert et al., 1973 Type species Shevyrevites shevyrevi Teichert & Kummel in Teichert et al., 1973, by original designation. Diagnosis Representatives of the family Xenodiscidae with a moderately large to large conch; maximum adult diameter between 60 and 80 mm. Subadult stage with a trapezoidal whorl profile, adult stage variable. Subadult stage with small to large conical ventrolateral nodes, adult stage with a weakening sculpture with predominant ribs. Suture line with external lobe that does not reach the depth of the adventive lobe; prongs of the external lobe simple or bifid. Included species Shevyrevites shevyrevi Teichert & Kummel in Teichert et al., 1973; Bernhardites nodosus Shevyrev, 1965; Shevyrevites corrugatus Korn & Hairapetian sp. nov. Remarks The species of Shevyrevites show a coarse ornament consisting of lateral ribs and sometimes also coarse conical nodes in the inner whorls, and are hereby clearly separated from the other genera of the family. Regarding the presence of ventrolateral nodes, there are some similarities to the genera of the family Dzhulfitidae, but these differ in the shape of the suture line: while the external lobe is wide in Shevyrevites, it is always narrow in the Dzhulfitidae. Teichert & Kummel (in Teichert et al. 1973) caused some nomenclatorial confusion with their opinion on the species of their new genus Shevyrevites. They made clear that “ Celtites radiosus ”, the Triassic type species of Bernhardites Shevyrev, 1965, differs from the Late Permian forms and that for the latter, a new genus name (Shevyrevites) had to be introduced. At the same time, they treated the two species “ Bernhardites radiosus (Frech in Noetling, 1905)” and “ Bernhardites nodosus Shevyrev, 1965 ”, both of which were separated by Shevyrev (1965), as synonyms; they described these under the new genus and species name Shevyrevites shevyrevi. This procedure is not accepTable because it suppresses the species name Shevyrevites nodosus, which in case of synonymy of the two species has priority over Shevyrevites shevyrevi. However, this problem is regarded here minor, as we accept both species as valid.Published as part of Korn, Dieter, Hairapetian, Vachik, Ghaderi, Abbas, Leda, Lucyna, Schobben, Martin & Akbari, Amir, 2021, The Changhsingian (Late Permian) ammonoids from Baghuk Mountain (Central Iran), pp. 1-106 in European Journal of Taxonomy 776 on page 18, DOI: 10.5852/ejt.2021.776.1559, http://zenodo.org/record/560471
Hemichoanella Teichert & Glenister 1954
No full textGenus Hemichoanella Teichert & Glenister, 1954 Type species Hemichoanella canningi Teichert & Glenister, 1954, from Emanuel Formation, stage III (Bendigonian– Chewtonian, see Legg 1978; Floian), Emanuel Creek, Kimberley Division, Western Australia; by original designation. Diagnosis Orthoconic longicones with circular conch cross section; sutures with deep, narrow siphonal lobe; siphuncle marginal, nearly tubular with rSD ≈ 0.3; septal necks hemichoanitic, connecting ring thick (compiled from Teichert & Glenister 1954 and Furnish & Glenister 1964). Remarks The genus is provisionally placed within the Cyptendoceratidae because of the presence of a relatively wide siphuncle with relatively long septal necks and concave, relatively thick connecting rings (see additional remarks below in chapter Cladistic Analysis).Published as part of Kröger, Björn & Pohle, Alexander, 2021, Early-Middle Ordovician cephalopods from Ny Friesland, Spitsbergen - a pelagic fauna with Laurentian affinities, pp. 1-102 in European Journal of Taxonomy 783 (1) on page 47, DOI: 10.5852/ejt.2021.783.1601, http://zenodo.org/record/579342

Diagnosis Species of Shevyrevites with conch reaching 70 mm dm. Subadult stage with oval, compressed whorl profile (ww/wh= 0.70–0.90) and rounded venter; 30 coarse ribs per volution.Adult stage with rectangular and compressed whorl profile (ww/wh =0.70–0.80), flattened flanks, flattened venter and subangular ventrolateral shoulder; coarse and sharp ribs on the flank, venter smooth. Prongs of external lobe usually bifid; altogether 20–25 notches of E, A and L lobes. Type material Holotype IRAN • East Azerbaijan, Ali Bashi Mountains; Ali Bashi Formation; illustrated by Teichert & Kummel in Teichert et al. (1973: pl. 3 figs 1–2); MCZ 9678. Material examined IRAN • 30 specimens; Esfahan Province, Baghuk Mountain 1 section; Hambast Formation; MB.C.29664 to MB.C.29669 • 4 specimens; Esfahan Province, Baghuk Mountain B section; Hambast Formation; MB.C.29670 to MB.C.29673 • 12 specimens; Esfahan Province, Baghuk Mountain E section; Hambast Formation; MB.C.29674 to MB.C.29678 • 2 specimens; Esfahan Province, Baghuk Mountain G section; Hambast Formation; MB.C.29679 • 33 specimens; Esfahan Province, Baghuk Mountain H section; Hambast Formation; MB.C.29680 to MB.C.29687 • 92 specimens; Esfahan Province, Baghuk Mountain; Hambast Formation; MB.C.29688 to MB.C.29712. Description There is little morphological variation in the material when the conch proportions are regarded. specimen MB.C.29674 is an incomplete but comparatively well-preserved specimen with 52 mm diameter (Fig. 17A). It is extremely discoidal (ww/wh =0.24) and evolute (uw/dm =0.48) with a compressed, parallel-sided whorl profile with flat venter and an angular ventrolateral shoulder. The sculpture consists, on the last volution of the phragmocone as well as the body chamber, of sharp and slightly sigmoidal ribs on the flanks; on half a volution around 20 of such ribs can be counted. The suture line of specimen MB.C.29674 has a short external lobe with concave flanks and bifid prongs (Fig. 17D). The ventrolateral saddle is asymmetric and appears dorsally inclined. The adventive lobe is semicircular in shape with twelve small notches of equal size. In contrast to this is the lateral lobe almost flat at its base; it is also serrated by numerous small notches. There is some variation in the shape of the venter. In contrast to specimen MB.C.29674, the other two figured specimens MB.C.29672 (Fig. 17B) and MB.C.29670 (Fig. 17C) show a less flattened or even a rounded venter. These two specimens do not show as sharp ribs as specimen MB.C.29674. Remarks Shevyrevites shevyrevi differs from S. nodosus in the lack of the coarse nodes of the subadult stage and from S. corrugatus sp. nov. in the much coarser and less numerous ribs. Stratigraphic range Upper part of the Hambast Formation; 5.20 to 4.70 m below the extinction horizon (Shevyrevites shevyrevi Zone).Published as part of Korn, Dieter, Hairapetian, Vachik, Ghaderi, Abbas, Leda, Lucyna, Schobben, Martin & Akbari, Amir, 2021, The Changhsingian (Late Permian) ammonoids from Baghuk Mountain (Central Iran), pp. 1-106 in European Journal of Taxonomy 776 on pages 19-21, DOI: 10.5852/ejt.2021.776.1559, http://zenodo.org/record/560471
