✦ Synopsis

A novel class of chiral glycosyl-triazole-based P,N ligands were synthesized by click chemistry and were applied to the Rh-catalyzed asymmetric hydrosilylation of a range of substituted acetophenones. Enantioselective hydrosilylation of acetophenone gave (S)-1-phenylethanol in moderate enantioselectivity (72% ee) and in good conversion (93%).
