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.

The chemoselective alkylation of tryptamine derivatives with 2-oxo-1-pyrrolidine compounds, catalyzed by In(OTf)3, was investigated. A series of 2-alkyl and N-alkyl tryptamine derivatives were synthesized under mild conditions with good total yields (up to 99%) and chemoselectivity (up to 95 : 5).
