The stereospecifically anti synthesis of allyl- and allenyl-silanes by the reaction of a silylcuprate reagent with allyl and propargyl acetates is described. The SE2′ reactions of these silanes with various electrophiles are shown to proceed with predominantly anti stereoselectivity, offset to a greater or lesser extent by other steric factors.
描述了通过甲硅烷基杯酸酯试剂与乙酸烯丙酯和炔丙基乙酸酯反应的烯丙基硅烷和烯丙基硅烷的立体有择抗合成。这些硅烷与各种亲电试剂的S E 2'反应显示出主要具有反立体选择性,但会被其他空间因素或多或少地抵消。
