Zinc Triflate Promoted General Synthetic Protocol for the Facile Construction of Chromenes and Pyrimidines Bearing N-Allyl Quinolone Nucleus

Full Text PDF

Abstract:

A series of 8 derivatives of chromene 5a-h synthesized via one-pot cyclocondensation reaction of N-allyl quinolones, α/β naphthol and malononitrile. And 8 derivatives of pyrimidines 8a-h bearing N-allyl quinolone have been synthesized by N-allyl quinolones, ethylacetoacetate, thiourea/urea in the presence of zinc triflate as less toxic catalyst. This methodology allowed the high conversion of product at room temperature. Titled derivatives were elucidated by FT-IR, 1H NMR, 13C NMR, elemental analysis, and mass spectral data.
