Regioselective Synthesis of Novel Perfluoroalkylated Fused Pyridines and 3-(Aminomethylene)thiochroman-4-ones from 3-(Perfluoroalkanoyl)thiochromenones and Amines
Regioselective Synthesis of Novel Perfluoroalkylated Fused Pyridines and 3-(Aminomethylene)thiochroman-4-ones from 3-(Perfluoroalkanoyl)thiochromenones and Amines
The regioselectivity of reactions of 3-(perfluoroacyl)-4H-thiochromen-4-ones with a range of hetaryl, aryl, and alkyl amines was examined. The reactions provide ready access to polyfluoroalkylated fused pyridines and thiochromen-4-ones.
