ketones have been obtained with a high level of selectivity from enolic α-keto esters in two steps, with the reduction of the α-silyloxy α,β-unsaturated ester by LiAlH4 as the key step. The methodology developed in this work represents a “reversed” chemoselective reduction of the ester group instead of the keto of an enolic α-keto ester due to a one-pot sequential ester reduction-desilylation or silyl migration
