摘要

2, 4, 6-Triaryl-3-methylarylpyridines were obtained, in 60–70% yield, by a novel one-pot solventless solid-supported dimerization–heteroannulation reaction of chalcones and compounds possessing terminal–CONH2 functionality, at 125–135° C, using immobilized Bi (III) nitrate and Zn (II) chloride as co-catalyst. Initially, chalcones were prepared, in nearly quantitative yield, by a modified aldol condensation, in neutral aqueous medium, in the ...
