Synthesis of a β-amino acid pharmacophore via a β-lactam intermediate

(Chemical Equation Presented) A stereoselective synthesis of (R)-β-amino acid 1 via a β-lactam intermediate is discussed.

PROCESS AND INTERMEDIATES FOR THE PREPARATION OF BETA-AMINO ACID AMIDE DIPEPTIDYL PEPTIDASE-IV INHIBITORS

A novel process is provided for the preparation of chiral beta-amino acid amide inhibitors of the dipeptidyl peptidase-IV 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.
