Derivatives of the Phe-alpha-methoxyglycine (4) were prepared and foun
d to undergo stereospecific intramolecular amidoalkylation to give der
ivatives of 4-amino-2-benzazepin-3-one-1-carboxylic acid 5 (ABZC). The
cyclic compounds 5a-g are conformationally restricted peptides contai
ning a bridged Phe-Gly moiety.
