Asymmetric silylation of alcohols is an unusual but effective approach to their kinetic resolution, and the Cu–H-catalyzed dehydrogenative Si–O coupling is particularly noteworthy as dihydrogen is formed as the sole by-product. Our laboratory had previously reported on diastereoselective (with silicon-stereogenic silanes) and enantioselective (with achiral silanes) Si–O couplings of azine donor-functionalized alcohols. The limitation, that ...
