An atroposelective Miyaura borylation of bromoarenes with unsymmetrical diboron reagents has been reported for the direct catalytic synthesis of optically active atropisomeric arylborons. This reaction exhibits broad substrate scope, high yields, and good enantioselectivities in producing axially chiral arylborons.
Compared with the well-developed centrally chiral boron chemistry, C-B axially chiral chemistry remains elusive and challenging. Herein we report the first atroposelective Miyaura borylation of bromoarenes with unsymmetrical diboron reagents for the direct catalytic synthesis of optically active atropisomeric arylborons. This reaction features broad substrate scope and produces axially chiral arylborons with high yields and good enantioselectivities.
