The synthetic versatility of 12-acetoxydrima-7,9(11)-diene 1 obtained from 15-hydroxylabda-7,13-dien-17-oic acid (zamoranic acid), as a key intermediate in the homochiral semisynthesis of highly functionalized drimanes such as pereniporin A 3, an important antibiotic, through the carbonate 2, is highlighted.

The paper describes a new pathway for an efficient synthesis of natural and bioactive drimanic compounds (-)-pereniporin B (1) and (-)-cinnamosmolide (2) from ketodiol 7, an intermediate obtained before from accessible labdane diterpenoid (+)-larixol (3). The key step involves allylic bromination of acetate 8 with N-bromosuccinimide. The in vitro antimicrobial and antifungal activities of all compounds are also reported. Their structures were confirmed by both spectroscopic data and chemical transformations.
