In situ-generated silyl methide species (R(3)Si-CTf(2)R') effectively catalyzed the reaction of beta-substituted alpha,beta-unsaturated aldehydes with silicon dienoates such as 3-bromo-2-TESO-furan to give the corresponding gamma-adducts with excellent 1,4-selectivity and good anti selectivity.
原位生成的甲硅烷基甲基化物物种(R(3)Si-CTf(2)R')有效催化β-取代的α,β-不饱和醛与硅二烯酸酯如3-溴-2-TESO-呋喃的反应得到具有优异的1,4-选择性和良好的抗选择性的相应的伽玛加合物。
