摘要

The synthesis is aimed at the unknown hydrocarbon 5, which is expectedlaSc to be thermally unstable with respect to 1. Although all attempts to convert the known ketone 9 directly to 5 by methylenation so far have led to intractable products, 6 two indirect methods are feasible (Scheme I).'Both involve protection of the endocyclic double bond of 9 before methylenation. In method A, the endocyclic double bond is restored by, respectively, a ...
