Reactions of α-trimethylsilylvinyl carbanions with carboxylic acid derivatives: the relationship between product distribution and substrate reactivity
Abstract
The reaction between α-trimethylsilylvinyl carbanions and carboxylic acid derivatives gives α,β-unsaturated carbonyl compounds which, under the reaction conditions, undergo further conjugate addition. Further reactions can also occur, depending upon the reactivities of the enolates and of the carboxylic acid derivatives.
