1,3-Oxazines and Related Compounds. VI. Synthesis and Some Reactions of 2,6-Disubstituted 4H-1,3-Thiazin-4-ones

Various of 2,6-disubstituted 4H-1,3-thizin-4-ones (5) were synthesized by successive treatment of N-acylacetylcarboxamides with acid (such as 70percent perchloric acid or fluorosulfonic acid) and hydrogen sulfide.Reactions of 5 were investigated; ammonolysis with ethanolic ammonia gave the corresponding pyrimidin-4-ones; hydrolysis of 2-alkyl-1,3-thiazine derivatives yielded ring-opend N-acyl-β-mercaptocrotonamides; reduction with NaBH4 or LiALH4 afforded 3,4-dihydro-2H-1,3-thiazin-4-one derivatives.Keywords - 1,3-thiazin-4-one; 3,4-dihydro-2H-1,3-thiazin-4-one; pyrimidin-4-one; 1,3-oxazinium salt; 1,3-thiazinium salt; N-acylacetylcarboxamide; N-acyl-β-mercaptocrotonamide
