An addition/cyclization reaction of 1,6-diynes was developed for the synthesis of highly substituted 1,2-dialkylidenecycloalkanes. In this work, 1,6-diynes reacted with (dimethylphenylsilyl)pinacol-borane in the presence of a palladium catalyst to afford 1,2-dialkylidenecycloalkanes bearing silyl and boryl groups with a (Z,Z)-configuration in good to excellent yields. Moreover, the corresponding products
开发了1,6-二炔的加成/环化反应,用于合成高度取代的1,2-二亚烷基环烷烃。在这项工作中,1,6-二炔与(二甲基苯基甲硅烷基)频哪醇-硼烷在钯催化剂的存在下反应,以良好的收率获得了具有(Z,Z)-构型的甲硅烷基和硼烷基的1,2-二亚烷基环烷烃。而且,相应的产物可以容易地转化成其他合成上有用的化合物。该协议为不饱和1,6-二炔的杂元素-元素键连接提供了一种有效且实用的方法。
