摘要

Abstract: A very general preparative method for homoallyllithiums consists of reductive lithiation of homoallyl phenyl sulfides by lithium 4, 4'-di-tert-butylbiphenylide. The sulfides can be prepared by a variety of methods including (1) the triethylamine-catalyzed addition of thiophenol to a conjugated enal or enone followed by a Wittig or Peterson olefination,(2) the reaction of a silyl enol ether with a diphenyl dithioacetal catalyzed by stannic chloride, ...
