Abstract
A reaction of 2-trifluoroacetyl-1H-benzo[f]chromenes with N-arylamides of cyanoacetic acid led to the synthesis of a series of 2-oxo-6-trifluoromethylpyridine-3-carboxamides as products of a cascade of the carbo-Michael reaction, Thorpe–Ziegler cyclization, and Dimroth rearrangement. In the case of 1H-benzo[f]chromene-2-carbaldehydes, the corresponding Knoevenagel adducts were isolated.
