Asymmetric hydrogenation of Ac-ΔTyr(Ac)-(S)-Ala-Gly-OMe (6), Ac-ΔTyr(Ac)-(R)-Ala-Gly-(S)-Phe-OMe (7), Ac-ΔPhe-NH-CH(R)-CH2-OCH2Ph (10), HCO-ΔPhe-(S)-Leu-OMe (16), X-AA-ΔPhe-AA'-OMe ( 5: X=tBOC, CBZ, CF3CO; AA, AA'= α-amino acid ), and t

SYNTHESIS OF ENKEPHALIN ANALOGS VIA ASYMMETRIC HYDROGENATION OF DEHYDROPEPTIDE BUILDING BLOCKS

1, D-Ala2, Leu5-OMe>Enkephalin and 1, D-Ala2, Leu5-OMe>Enkephalin were succesfully synthesized by the coupling of dipeptide units and tripeptide units which were readily obt

Synthesis of Chiral Dipeptides by means of Asymmetric Hydrogenation of Dehydro Dipeptides

Asymmetric hydrogenation of various dehydro dipeptides was carried out by using rhodium complex catalysts with a variety of chiral diphosphine ligands.The efficiency of chiral diphosphine ligands as well as the effect of the chiral center in the substrate
