Abstract

A previous paper from these laboratories detailed the use of y-silyloxy vinyl sulfones 2 (Scheme 1) as the focal point of a four-step synthesis of a, &disubstituted enones 4.2 A serious deficiency of this strategy has been revealed by our recent need for@-substituted enones which bear a hydrogen in the a-position (4, R1= H). 3 This limitation has now been removed for six-and seven-membered rings by implementation of an alternative onepot ...
