Abstract

Abstract 2, 3-Disubstituted-pyrido [3′, 2′: 4, 5] thieno [3, 2-d] pyrimidin-4 (3H)-ones 8a-8c, 9a-9c were obtained by treatment of pyrido [3′, 2′: 4, 5] thieno [3, 2-d][1, 3] oxazin-4 (3H)- one derivative 3, 3-diacetylamino-thieno [2, 3-b] pyridine derivative 5 and 3- ethoxymethyleneaminothieno [2, 3-b] pyridine derivative 7a with appropriate amines, respectively. Condensation of compounds 8b, 9b with appropriate α-chlorocarbonyl ...
