trimethylsilyl phosphite (DTMSP) with aldehydes were converted, by treatment with lithium diisopropylamide (LDA) followed by the successive alkylation and alkaline hydrolysis, to carbonyl derivatives involving aldehydes, unsymmetrical ketones, β,γ-unsaturated ketones, and carboxylic acids. β-Substituted carboxylic esters and γ-substituted lactones were prepared by use of the carbonyl addition compounds of DTMSP
通过用二异丙基氨基锂 (LDA) 处理,然后连续烷基化和碱水解,将二乙基三甲基甲硅烷基亚磷酸酯 (DTMSP) 与醛的羰基加成化合物转化为涉及醛、不对称酮、β,γ-不饱和酮和羧酸的羰基衍生物酸。利用DTMSP的羰基加成化合物与α,β-不饱和醛制备β-取代羧酸酯和γ-取代内酯。
