Significance

A stereoconvergent asymmetric Suzuki coupling of racemic α-chloroamides and Ar-(9-BBN) is reported. The group’s earlier work on the Negishi, Hiyama, and Kumada coupling of α-bromoketones paved the way for this work. There are few examples of Suzuki couplings forming either alkyl-alkyl or aryl-aryl bonds enantio­selectively, and this is the first example of an ­enantioselective Suzuki coupling of an aryl-boron reagent with activated alkyl-halide electrophiles.
