Chemistry of zamoranic acid. Part 10. Homochiral hemisynthesis of pereniporin A

Abstract

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.
