thiazole-4-carboxylic acids into the 4-acetamido-compounds, which are degraded directly by acid hydrolysis leaving the 2-carbon atom, in the form of a carboxyl group, as remnant of the thiazole ring. For example 2′-phenyl-2,4′-bithiazolyl-4-carboxylic acid was degraded to 2-phenylthiazole-4-carboxylic acid, which was degraded to benzoic acid, and 2-(1-amino-2-methylpropyl)thiazole-4-carboxylic acid, a hydrolysis
Curtius反应已用于将2-取代的噻唑-4-羧酸转化为4-乙酰氨基化合物,这些化合物可通过酸水解直接降解,以羧基的形式留下2-碳原子,如噻唑环的残基。例如,将2'-苯基-2,4'-噻唑基-4-羧酸降解为2-苯基噻唑-4-羧酸(其降解为苯甲酸)和2-(1-氨基-2-甲基丙基)噻唑微球菌素P的水解产物-4-羧酸降解为缬氨酸。
