Meridane and uladane, two unprecedented sesquiterpene skeletons obtained by Wagner-Meerwein rearrangements of Longipinane derivatives

Abstract:

Three new tricyclic structures were obtained from 7β-hydroxy-9-oxolongipin-2-en-1-one (2). Compounds 4 and 5 contain both a new carbocyclic skeleton and therefore were named as meridane (4) and uladane (5). Formation of these products (4 and 5) can be explained by reaction mechanisms, involving Wagner-Meerwein rearrangements.
