An enantioconvergent approach for direct asymmetric insertion of racemic carbon-, oxygen-, nitrogen-, sulfur- and silicon-substituted carbenoids into carbon–boron bonds is reported, enabled by a class of chiral β-amino alcohol auxiliaries. In addition, iterative asymmetric homologation offered by this method simplifies syntheses of complex molecules containing multiple stereocentres.
