Popis:	Acylation of 2H-thiopyran-3,5(4H,6H)-dione and 2-methyl-2H-thiopyran-3,5(4H,6H)-dione with acetyl chloride or propionyl chloride afforded the corresponding 4-acyl-2H-thiopyran-3,5(4H,6H)-diones. Oxidation of 4-acetyl-2H-thiopyran-3,5(4H,6H)-dione with m-chloroperoxybenzoic acid gave 4-acetyl-2H-thiopyran-3,5(4H,6H)-dione 1-oxide. 4-Acyl-2H-thiopyran-3,5(4H,6H)-diones and 4-acetyl-2H-thiopyran-3,5(4H,6H)-dione 1-oxide reacted with pyrrolidine, allylamine, and p-anisidine, resulting in formation of the corresponding 4-aminomethylene derivatives.
