Cyanamides in the synthesis of 1,3-thiazole and 1,3-thiazine derivatives
摘要:
Hetaryl, aroyl, and aryl cyanamides react with 2-sulfanylbenzoic acid, 2-aminobenzenethiol, and 2-aminoethanethiol to give derivatives of 2-amino-4H-1,3-benzothiazin-4-one, 1,3-benzothiazol-2-amine, and 4,5-dihydro-1,3-thiazol-2-amine.
