Abstract

Abstract Readily available 5-acyl-4-hydroxy-3, 6-dihydro-2 H-1, 3-thiazine-2, 6-diones with primary alkyl-and arylamines in mild conditions (boiling in propan-2-ol) to give Schiff bases. In more rigid conditions (boiling in DMF), the reaction is accompanied by COS liberation and provides 1-substituted 6-alkyluracils. This previously unknown reaction possesses a considerable synthetic potential and can be considered as a new, general, and ...
