An enantioselective, redox-relay Heck alkenylation of trisubstituted allylic alkenol substrates has been developed. This process enables the construction of vicinal stereocenters in high diastereo- and enantioselectivity and allows the formation of enolizable α-carbonyl methyl-substituted stereocenters with no observed epimerization under the reported reaction conditions.
已经开发了三取代的烯丙基烯醇底物的对映选择性,氧化还原-继电器的Heck烯基化。该方法使得能够以高非对映体和对映体选择性构建邻位立体中心,并且允许形成可烯丙基的α-羰基甲基取代的立体中心,而在所报道的反应条件下没有观察到差向异构。
