Title: Conjugate Reduction of a,b-Unsaturated Carbonyl Compounds. Selective Inhibition of Benzyl Ether Hydrogenolysis by NH4OH/MeOH
Author: Dias, Luiz C.
Campano, Priscila L.
Abstract: A series of a,b-unsaturated alkyl and aryl ketones, esters and N-methoxy-N-methyl-amides (Weinreb amides) containing an O-benzyl protecting group undergo conjugate reduction by H2/Pd/C in the presence of 2N NH4OH/MeOH at room temperature and ordinary pressure leaving the benzyl group intact
