标题:Method for the synthesis of axially chiral organoboron compounds

摘要:A highly efficient and atroposelective Rh-catalyzed [2+2+2] cycloaddition for the synthesis of axially chiral aryboron compounds is developed. The reactions of diynes and alkynylborons smoothly occur in an atom-economical manner, affording a variety of C—B atropisomers in excellent yields and enantioselectivities. The protocol features mild conditions, broad substrate scope, and good functional tolerance. The obtained C—B atropisomers show powerful synthetic applications in terms of producing novel chiral phosphine ligands.
