Abstract
A series of alpha,beta-unsaturated alkyl and aryl ketones, esters and N-methoxy-N-methyl-amides (Weinreb amides) containing an O-benzyl prot ecting group undergo conjugate reduction by H-2/Pd/C in the presence o f 2N NH4OH/MeOH at room temperature and ordinary pressure leaving the benzyl group intact.
