A versatile and convenient method for the preparation of α-(Z)-1-alkenyl ketones from β-keto benzyl esters
Abstract
A versatile and selective method for the preparation of α-(Z)-1-alkenyl ketones from -keto benzyl esters has been developed by exploiting the three-step sequence of an improved Pinhey's alkynylation, semihydrogenation, and reductive debenzyloxycarbonylation.
