A synthetic method for azaheterocycles from aryl ketone O-acetyl oximes and internal alkynes has been developed by using the Cu(OAc)2–[Cp*RhCl2]2 bimetallic catalytic system. The reactions proceeded with both of anti- and syn-isomers of oximes with a wide scope of substituents. The Cu–Rh bimetallic system could be applied for the synthesis of isoquinolines as well as β-carboline, furo[2.3-c]pyridine
利用Cu(OAc)2- [Cp * RhCl 2 ] 2双金属催化体系,开发了一种由芳基酮O-乙酰基肟和内部炔烃合成氮杂杂环的方法。该反应在具有广泛取代基的肟的反-和顺-异构体上进行。Cu-Rh双金属系统可用于合成异喹啉以及β-咔啉,呋喃[2.3- c ]吡啶,吡咯并[2,3- c ]吡啶和噻吩并[2,3- c ]吡啶衍生物。
