Abstract

Degradations of ormosanine, C20H35N3, are described which are in agreement with structure II (8) for this alkaloid. Nuclear magnetic resonance study of N-acetyl and N-nitroso derivatives has been used to clarify the environment of the secondary nitrogen atoms. Chemical and spectroscopic evidence leads to the formulation XV b for the related alkaloid ormojanine, C20H31N3. Both alkaloids were found to give 3-n-pentyl-6, 8- ...
