Boron-stereogenic and C–B axially chiral compounds featuring boron-based chirality represent a rarely explored class of chiral scaffolds. Here, the authors report an asymmetric access to boron-stereogenic and C–B axially chiral (hetero)cycles via rhodium-catalyzed C–H activation of (hetero)arenes en route to [4 + 2] or [3 + 2] annulation with two classes of boron-functionalized alkynes.
