Abstract

Treatment of N-methylmorpholinium 5-cyano-2-oxo-4-(2-thienyl)-1,2,3,4-tetrahydropyridine-6-thiolate with α-bromo ketones in ethanol gives a 1:1 mixture of the corresponding 6-alkylthiopyridines and thiazolo[3,2-a]pyridines which are used in the synthesis of substituted 1-acyl-6-alkylthiopyridines and thieno[2,3-b]pyridines.
