A general method for alkali-metal-promoted reductive difunctionalization of alkenes has been developed by means of reduction-resistant alkoxy-substituted electrophiles. A series of 1,2-diboration and 1,2-dicarbofunctionalization products can be synthesized by employing trimethoxyborane and strained cyclic ethers such as oxirane and oxetane. In addition, unsymmetrical carbo- or thioborations have been
已经通过抗还原性烷氧基取代的亲电试剂开发了用于碱金属促进的烯烃的还原性双官能化的通用方法。通过使用三甲氧基硼烷和张力环醚(如环氧乙烷和氧杂环丁烷)可以合成一系列的1,2-二硼酸酯化和1,2-二氨基官能化产物。另外,已经通过依次用三甲氧基硼烷和碳或硫亲电试剂处理来实现不对称的碳硼或硫硼酸酯化。
