As a demonstration for an easy supply of the enantiomerically pure intermediate for the synthesis of labdane diterpenoids, stereocontrolled synthesis of (+)-acuminolide was achieved, and its absolute configuration was determined.
Common synthetic strategy for optically active cyclic terpenoids having a 1,1,5-trimethyl-trans-decalin nucleus: syntheses of (+)-acuminolide, (−)-spongianolide A, and (+)-scalarenedial
method for providing enantiomerically pure bi-, tri-, and tetracyclicframeworks having a 1,1,5-trimethyl-trans-decalin nucleus, and demonstrated their utility for terpenoid synthesis. Thus, we achieved the stereocontrolled total syntheses of (+)-acuminolide as a bicyclic, (−)-spongianolide A as a tricyclic, and (+)-scalarenedial as a tetracyclic terpenoid from the corresponding optically pure cyclic

AbstractA total synthesis of both the enantiomers of zonarol 1 was accomplished. Measurements of the ORD‐CD spectra of two bicyclic intermediates coupled with direct comparison of the natural and synthetic zonarol 1 established the absolute configuration of the naturally occurring (+)‐zonarol 1 as 1R, 4aR, 8aR.
