Biogenetic concepts in terpene structure elucidation
No full textIn the development of Natural Products Chemistry,biogenetic
considerations have played an important and useful role. In
this article, the author cites examples from his work in the area of Terpene Chemistry to highlight the usefulness of these concepts. To illustrate their application in structure elucidation, an example each from sesquiterpene, diterpene, triterpene and sesterterpene chemistry
has been described. Role of these concepts in the search for new structural types, congeners and precursors has been brought out. The usefulness of Absolute Stereochemistry Biogenetic Rule has been pointed out
Studies in sesquiterpenes-XVIII. The proton magnetic resonance spectra of some sesquiterpenes and the structure of humulene
No full textThe nuclear magnetic resonance spectra of longifolene, zerumbone, humulene, and their hydroderivatives have been studied in order to gauge the potentialities of this new tool in the field of sesquiterpenes. On the basis of present study, it has been possible to unequivocally fix the positions of the ethylene linkages in humulene and thus provide a straightforward solution of this hitherto unsolved problem

ACTION OF PREVOSTS REAGENT ON ∆ 9:10-OCTALIN
No full textThe action of silver benzoate-iodine complex on ∆9:10-octalin has yielded 9-oxy-∆4-octalin instead of the expected 9 : 10-glycol
STRUCTURE OF A BY-PRODUCT OBTAINED DURING THE CLEMMENSEN REDUCTION OF β-(p-CYMOYL-2)-PROPIONIC ACID
No full textA by-product, m. p. 210-11°. obtained during the Clemmensen reduction of β-(p-cymoyl-2)- propionic acid, has been found to be a. pioacol-dilactone. The structure has been confirmed by synthesis
