An efficient C(sp3)-H bond activation and intramolecular amination reaction via palladium catalysis at the β-position of carboxyamides to make β-lactams was described. The investigation of the substrate scope showed that the current reaction conditions favored activation of the β-methylene group. Short sequences were developed for preparation of various diazabicyclic β-lactam compounds with this method as the key step from chiral proline and piperidine derivatives.

Polypeptides of relatively low molecular weight and small size; namely derivatives of 4-amino-3-hydroxy-4--substituted butanoic acids and 5-amino-2,5-disubstituted--4-hydroxypentunoic acids for use as inhibitors of the cleavage of angiotensinogen by renin
