Abstract
The reactions of some alkoxycarbonyl isothiocyanates (2) with 2-aminothiazol (15) afforded thiazolo[3, 2-a]-S-triazine-4-thio-2-one (27), N-alkoxycarbonyl-N'-(2-thiazolyl)-thuoureas (A), alkyl-N-(2-thiazolyl)carbamates (B), N-alkoxycarbonyl thiocarbamates (C) and thiocyanic acid (31). However, in the case using phenoxycarbonyl isothiocyanate (59), the corresponding 1 : 1 adduct of (59) and (15) could not be obtained, but thiazolo-[3, 2-a]-s-thiazine-2-thio-4-one (32) was isolated, besides the cyclic compound (27), thiazolyl carbamate (60) and phenol.
