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.

An efficient method to synthesize the β-lactams with high regioselectivity via Pd-catalyzed C(sp3)-H bond activation and intramolecular amination of simple and readily available aminoquinoline carboxamides was demonstrated. C6F5I plays a signif
