Use of allylic strain to enforce stereochemistry. Direct syntheses of 7,8-dihydroxycalamenene and mansonone C.

George A Kraus1, Insik Jeon.   

Abstract

[Structure: see text] Direct syntheses of 7,8-dihydroxycalamenene and mansonone C were achieved. The cis-stereochemistry required for the synthesis of 7,8-dihydroxycalamenene was introduced by an intramolecular cyclization directed by allylic strain.
