Copper-catalyzed boroacylation of allenes to access tetrasubstituted vinylboronates

Bing-Xue Shen, Xiang‐Ting Min, Yan‐Cheng Hu, Lei-Lei Qian et autres

A distinct copper-catalyzed boroacylation of allenes with acyl chlorides and bis(pinacolato)diboron is developed. For aromatic acyl chlorides, 1,2-boroacylation of allenes readily takes place, leading to the formation of tetrasubstituted vinylboronates with exclusive (E)-stereoselectivity. In comparison, the employment of alkyl acyl chlorides as …
