| Abstract: | A new 3-(3'-pyridyl-formoylamino)-thiocarbonyl-2, 4-dioxopentance (2) was synthesized and the behavior of cyclisation of compound (2) in the presence of KOH was studied.The result shows that the reactiun of compound(2) in an alkaline medium gave 5-acetyl-6-inethyl2- (3'-pyridyl)-4-thioxo-1, 3-(4H) oxazine (3). The structures uf compounds prepared were characterized by elementary analysis, IR and 1HNMR. |
