Synthesis of β-, γ-, and δ-Lactams via Pd(II)-Catalyzed C−H Activation Reactions
摘要:
Pd(II)-catalyzed intramolecular amination of Sp(2) and Sp(3) C-H bonds are developed using a combination of CuCl2 and AgOAc as the oxidant. The reaction protocol tolerates the presence of a double bond in the substrates. This catalytic reaction provides practical access to a wide range of beta-, gamma-, and delta-lactams.

A novel catalytic method for synthesizing 4-aryl-2-quinolinones is reported. The process involves two mechanistically independent, sequential Pd(II)-catalyzed reactions--the oxidative Heck reaction and the intramolecular C-H amidation--both of which smoothly proceed in the presence of a single catalytic system in a one-pot manner.
