Preparation of bicyclic compounds from the products of conjugate addition of allylic sulphoxide and phosphine oxide carbanions to cyclopent-2-enones
Abstract
The conversion of the compounds obtained from the conjugate addition of the carbanions of allylic sulphoxides and phosphine oxides into bicyclo[3.3.0]octanes, bicyclo[2.2.1]heptanes, and bicyclo[3.2.1]octanes whose configurations reflect those of the starting compounds is described.
