A simple synthesis of (Z)-2-trimethylsilylmethyl-2-buten-1-ol from 2-butyn-1-ol provides ready access to disubstituted bifunctional conjunctive reagents such as the title compound. Palladium(0) catalysts initiate cycloaddition to electron-deficient olefins to form methylenecyclopentanes with excellent regioselectivity.
通过从 2-丁炔-1-醇简单合成 (Z)-2-三甲基硅甲基-2-丁烯-1-醇,可以直接获得标题化合物等二取代双官能团连接试剂。钯(0)催化剂可以启动缺电子烯烃的环化反应,生成具有优异区域选择性的亚甲基环戊烷。
