Abstract

Methyl 14, 15-dinor-13-oxo-7-labden-15-oate was obtained from acid zamoranic acid methyl ester. The former by photochemical cleavage yielded methyl 7, 9 (11)-drimadien-12-oate, whose chemoselective epoxidation afforded methyl 9α, 11-epoxy-7-drimen-12-oate, which is the key synthetic precursor for pereniporin B, polygodial and warbuganal.
