摘要:
An efficient synthesis of isoquinolines via Rh(III)-catalyzed oxidative annulation of picolinamides with alkynes using Cu(OAc)(2) as an oxidant has been developed. The scope of the reaction was studied with a selection of various picolinamides and alkynes, and the desired isoquinolines were obtained in good to excellent yields.
