Yang, Zhantao,Yang, Chun-Hua,Chen, Shiqi,Chen, Xixi,Zhang, Litian,Ren, Huijun

, p. 12092 - 12095 (2017/11/14)

A direct and catalyst-free annulative thioboration of unfunctionalized olefins has been developed. In the presence of BCl3 as the sole boron source, the boryl group and thiol group are added to the C-C double bonds simultaneously. The boronic acids obtained can be protected to form synthetically ubiquitous pinacol boronate esters.
