SYNTHESIS OF A PROTECTED MONODEHYDRO Leu-ENKEPHALIN AND ITS HYDROGENATION CATALYZED BY CHIRAL RHODIUM COMPLEXES

(S,S)-Z-(O)Ts-Tyr-Gly2-ΔPhe-Leu-OMe was synthesized.Some chiral rhodium complexes catalyze the reduction of the C=C bond.The stereochemistry of reduction of the ΔPhe moiety was investigated. 93 percent de could be achieved with dipamp as ligand in the cat
