An operationally convenient Mg-catalyzed synthesis of alcohols by the reduction of aldehydes, ketones and α,β-unsaturated aldehydes/ketones is reported. It is a rare example of using mild and sustainable HBpin as a reductant for catalytic reduction of carbonyl compounds in the absence of acid or base as hydrolysis reagent. The reaction is up-scalable, and proceeds in high selectivity without the formation of boronate ester by-products, and tolerates sensitive functionalities such as iodine, bromide, chloride, fluoride, nitro, trifluoromethyl, aminomethyl, alkynyl, and amide. The MgCl2/HBpin combination has been also proved to be chemoselective for the C=N reduction of imine analogs.
