Abstract

α,β-Unsatd. carbonyl compds. were cyclized with sulfonium ylides, the carbonyl compds. so formed were converted to alcs. by either using LiAlH4 or Grignard reagents. The alcs. were oxidized to β,γ-unsatd. carbonyl compds. using pyridinium chlorochromate (PCC), dichloromethane and water. Thus prepd. were 46-57% BzCH2CH:C(R)Ph (R = H, Ph, CH2Ph, p-tolyl).
