TARTARIC ACID SALTS OF A DIPEPTIDYL PEPTIDASE-IV INHIBITOR

Tartaric acid salts of (3R)-4-[(3R)-3-amino-4-(2,4,5-trifluorophenyl) butanoyl]hexahydro-3-(2,2,2-trifluoroethyl)-2H-1,4-diazepin-2-one are potent inhibitors of dipeptidyl peptidase-IV and are useful for the prevention and/or treatment of non-insulin depe

PROCESS TO CHIRAL BETA AMINO ACID DERIVATIVES BY ASYMMETRIC HYDROGENATION

The present invention relates to a process for the efficient preparation of enantiomerically enriched beta amino acid derivatives which are useful in the asymmetric synthesis of biologically active molecules. The process comprises an enantioselective hydrogenation of a prochiral beta amino acrylic acid derivative substrate in the presence of a transition metal precursor complexed with a chiral ferrocenyl diphosphine ligand with in situ protection of the primary amine product. The invention also relates to a novel process for the preparation of chiral beta-amino acid amides as inhibitors of the dipeptidyl peptidase-IV of structural formula III and the useful intermediates obtained therein. The products resulting from the instant process are inhibitors of dipeptidyl peptidase-IV and thereby useful for the treatment of Type 2 diabetes.
