Enantioselective synthesis of synthetically significant (α‐hydroxyallyl)silanes, (α‐hydroxyaryl)silanes, and (α‐hydroxyalkyl)silanes is reported. The present copper‐catalyzed 1,2‐selective hydroborylation of acylsilanes affords the aforementioned products in high yields and with high enantiomeric excesses. This robust and scalable additive‐free catalytic system relies on the use of low copper(II) acetate

The first intermolecular Schmidt reaction of alkyl azides with acyl silanes has been designed and realized, producing a range of amides with absolute site selectivity in good to excellent yields. The mechanism of the conversion has been proposed, and the reaction exhibits scope of substrates.

Metal-catalyzed enantioconvergent cross-coupling reactions of alkyl electrophiles are emerging as a powerful tool in asymmetricsynthesis. To date, high enantioselectivity has been limited to couplings of electrophiles that bear a directing group or a proximal p/π orbital. Herein, we demonstrate for the first time that enantioconvergent cross-couplings can be achieved with electrophiles that lack such
