applicable synthesis of alpha,alpha-disubstituted beta-ketoesters involving reaction of a substituted benzoyl chloride with methyl trimethylsilyl ketene acetal is described. Addition of boron trifluoride etherate is essential when the benzoyl chloride is nor substituted with a strongly electron withdrawing residue. The majority of experiments were conducted with the dimethylketene acetal but the process
描述了一种普遍适用的 α,α-二取代 β-酮酯合成,包括取代苯甲酰氯与甲基三甲基甲硅烷基乙烯酮缩醛的反应。当苯甲酰氯未被强吸电子残基取代时,添加三氟化硼醚合物是必不可少的。大多数实验是用二甲基乙烯酮缩醛进行的,但该过程同样适用于环己烷乙烯酮缩醛 5。
