The stereochemical outcome of the carbocupration of γ-bis(trimethylsilyl)amino-α-acetylenic amide, esters and ketone was studied. A judicious choice of substrate, reagent and(or) reaction conditions allows to perform highly stereoselective cis or trans addition. The intermediate vinylic copper adducts, with (E) or (Z) configuration, react with electrophilic reagents to provide short routes to substituted
研究了γ-双(三甲基甲硅烷基)氨基-α-炔酰胺,酯和酮的碳掩埋的立体化学结果。对底物,试剂和/或反应条件的明智选择允许进行高度立体选择性的顺式或反式添加。具有(E)或(Z)构型的中间乙烯基铜加合物与亲电试剂反应,以提供通往取代的吡咯烷酮和吡咯的短路径。
