Ruthenium-Catalyzed Highly Regioselective Cyclization of Ketoximes with Alkynes by C–H Bond Activation: A Practical Route to Synthesize Substituted Isoquinolines
摘要:
Aromatic and heteroaromatic ketoximes underwent cyclization with alkynes in the presence of a catalytic amount of [{RuCl2(p-cymene)}(2)] and NaOAc to give isoquinoline derivatives in good to excellent yields in a highly regioselective manner.
