Abstract
The selectivity of the reactions of 3-(polyfluoroacyl)-4H-chromen-4-ones with a wide range of aminoheterocycles and arylamines has been evaluated. The method described facilitates access to polyfluoroalkyl-containing fused pyridines.
Key words
aminoheterocycles - arylamines - condensation - chroman-4-ones - polyfluoroalkyl - fused pyridines
