Although asym. C-H functionalization was available for the synthesis of structurally diverse mols., catalytic dynamic kinetic resolution (DKR) approaches to change racemic stereogenic axes remain synthetic challenges in this field. Here, a concise Pd-catalyzed DKR was combined with C-H functionalization involving olefination and alkynylation for the highly efficient synthesis of nonbiaryl-atropisomer-type (NBA) axially chiral organosilanes. The chem. proceeded through two different and distinct DKR: 1st, an atroposelective C-H olefination or alkynylation produced axially chiral vinylsilanes or alkynylsilanes as a new family of nonbiaryl atropisomers (NBA), and 2nd, the extension of this DKR strategy to 2-fold o,o’-C-H functionalization led to the multifunctional axially chiral organosilicon compounds with up to >99% ee.
