Cu(OTf)2 catalyzed cross-coupling reaction of 1,3-dicarbonyl derivatives with 2-oxo-1-pyrrolidine compounds
摘要:
An efficient method for the cross-coupling reactions of 1,3-dicarbonyl compounds with 2-oxo-1-pyrrolidine compounds 1 was developed. Cu(OTf)(2) catalyzed C-C bond forming reactions using substrates 1 with 1,3-dicarbonyl compounds in chloroform, providing the corresponding compounds of 2-oxo-1-pyrrolidine bearing 1,3-dicarbonyl moiety in moderate to good yields.
