BCl 3是一种廉价的亲电试剂,它能诱导多种取代炔的硼化环化反应,区域选择性地形成含有多功能C(sp 2)-取代硼酸酯的多环化合物。它进行迅速,具有良好的产率,并与一系列官能团和取代模式兼容。炔的分子间1,2-碳硼化也可以使用BCl 3来实现,以生成三取代的乙烯基硼酸酯。
BCl3is an inexpensive electrophile which induces the borylative cyclization of a wide range of substituted alkynes to regioselectively form polycycles containing synthetically versatile C(sp2)boronate esters. It proceeds rapidly, with good yields and is compatible with a range of functional groups and substitution patterns. Intermolecular 1,2‐carboboration of alkynes is also achieved using BCl3to generate trisubstituted vinyl boronate esters.
