A series of dihomodrimane sesquiterpenoids containing an NH 2 group were synthesized. 11-Dihomodriman-8D-ol-12-one and its dehydration products, ketones with double bonds in the C 7 -C 8 and C 8 -C 9 positions, were prepared from commercially available norambreinolide. The oximes of the ketones were reduced by LiAlH 4 to the corresponding amines.
Amides of ' 8,13 -bicyclohomofarnesoic acid containing 1,2,4-triazole and carbazole rings were synthesized in eight steps from commercially available norambreinolide. The compounds were prepared by reacting the acid chloride with the heterocyclic amines 3-amino-1,2,4-triazole and N-aminocarbazole. Their structures were elucidated by spectral methods and x-ray crystal structure analyses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
