Drimanes plant growth activity

The diverse biological activity (e.g. insect antifeeding, plant growth regulation, molluscicidal) of a number of drimane sesquiterpenoids has stimulated considerable interest in their synthesis and the year under review has seen many new developments and improvements. Much of the synthetic work has centred around the key bicyclic diester (54) derived from 1-vinyl-2,6,6-trimethylcyclohexene and dimethyl acetylenedicarboxylate. In contrast to earlier results,34 Ley et al.8S...
