ASYMMETRIC CATALYSIS

Chiral γ-lactam synthesis via asymmetric C–H amidation

The asymmetric synthesis of chiral γ-lactams is difficult and laborious; typically requiring pre-functionalization of starting materials. Now, a highly efficient alternative approach employing direct C−H amidation via chiral hydrogen-bond-donor catalysts has been developed.
