Methyl 2-triorganosilyl-3-butenoates, which are selectively obtained from the carboxylation of the corresponding allylsilanes via allylic aluminates, react with various kinds of electrophiles to give γ substituted (E)-α,β-unsaturated esters in highly regio and stereoselective manner with the aid of a Lewis acid.
甲基2-三有机硅基-3-丁烯酸酯,通过烯丙基铝酸盐途径从相应的烯丙基硅烷进行羧基化选择性制备得到,在Lewis酸的辅助下,能高度区域选择性和立体选择性地与各种亲电试剂反应,生成γ取代的(E)-α,β-不饱和酯。
