    Tlacuatzin Voss and Jansa 2003

    Genus <i>Tlacuatzin</i> Voss and Jansa, 2003 <p> TYPE SPECIES: <i>Didelphis</i> (<i>Micoureus</i>) <i>canescens</i> J.A. Allen, 1893, by original designation.</p> <p>SYNONYMS: None.</p> <p> REMARKS: See Voss and Jansa (2009) for an emended generic description. The relationships of <i>Tlacuatzin</i> within the tribe Marmosini have yet to be satisfactorily resolved, although the largest concatenated-gene dataset yet analyzed (Amador and Giannini, 2016) suggests that it is the sister group to <i>Marmosa.</i></p> <p> Arcangeli et al. (2018) recognized five species of this Mexican endemic genus based on phylogenetic analyses of sequence data from one mitochondrial gene (cytochrome <i>b</i>) and one nuclear gene (IRBP). Unfortunately, only cytochrome <i>b</i> was taxonomically informative, and taxonomic differences in morphological traits were not convincingly documented. In the absence of compelling evidence for nucleargene divergence, the following taxa are perhaps nothing more than mtDNA haplogroups; alternatively, they might be treated as subspecies. However, until relevant phenotypic analyses or additional genetic analyses are carried out, I list them here as valid species.</p>Published as part of <i>Voss, Robert S., 2022, An Annotated Checklist Of Recent Opossums (Mammalia: Didelphidae), pp. 1-77 in Bulletin of the American Museum of Natural History 2022 (455)</i> on page 30, DOI: 10.1206/0003-0090.455.1.1, <a href="http://zenodo.org/record/7161371">http://zenodo.org/record/7161371</a&gt

    Derivatives of 1,2,3,4-Tetrahydroisoquinoline-3-carboxylic Acid

    No full text
    The following derivatives of 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid have been prepared in their (S)-form and as racemates: hydrochloride of methyl ester, N-carboxy anhydride, and N-acetyl derivative. All the substances were fully characterised by elemental analyses, H-1 and C-13 NMR spectra, and optical rotation, as the case may be; the M-carboxy anhydride was also characterised by means of X-Ray diffraction. Also identified was the intermediate of the reaction of the title acid with phosgene, the N-chlorocarbonyl derivative, and the respective methyl ester was prepared. The dioxopiperazine of the title acid was prepared and characterised both in pure (S,S)-form and in the form of a mixture of two racemates. The optically pure dioxopiperazine was prepared by a reaction of the N-carboxy anhydride in solid phase

    The reaction of methyl (S)-1,2,3,4-tetrahydroisoquinoline-3-carboxylate with isocyanates (phenyl, naphthalen-1-yl, cyclohexyl, (S)-1-methylbenzyl) in ether has been used to prepare N-substituted methyl (3S)-2-aminocarbonyl-1,2,3,4-tetrahydroisoquinoline-3-carboxylates. These compounds were cyclised by action of CF3COOH to give the corresponding 2-substituted (10aS)-10,10a-dihydroimidazo[1,5-b]isoquinoline-1,3(2H,5H)-diones (hydantoins Tic-H). Hydantoins Tic-H were also prepared by the reaction of methyl (S)-1,2,3,4-tetrahydroisoquinoline-3-carboxylate with isocyanates (methyl, (1S)-1-methylbenzyl, 4-methylphenyl, 3-methylphenyl, 4-chlorophenyl, 2,4-dichlorophenyl, 4-methoxyphenyl, 5-chloro-2-methoxyphenyl, 3-chloro-4-ethoxyphenyl) and triethylamine in CH2Cl2. 2-Substituted (10aS)-3-thioxo-1,2,3,5,10,10a-hexahydroimidazo[1,5-b]isoquinolin-1-ones (thiohydantoins Tic-TH) were prepared analogously by the reaction of methyl (S)-1,2,3,4-tetrahydroisoquinoline-3-carboxylate with isothiocyanates (methyl, ethyl, allyl, phenyl). The optical purity of selected substances was determined chromatographically
