4-Amino-3-arylisothiazole-5-carboxylate esters are converted to the corresponding desamino, chloro, bromo, and iodo esters by processes involving nonaqueous diazotization. These related procedures open up the possibility for the conversion of readily available heterocyclic ortho-amino esters and nitriles to related heterocyclic derivatives, which are not easily obtained by alternate routes.
通过涉及非水重氮化的方法,将4-氨基-3-芳基噻唑-5-羧酸酯转化为相应的脱氨基,氯代,溴代和碘代酯。这些相关的程序为容易获得的杂环邻氨基酯和腈转化为相关的杂环衍生物提供了可能性,而这些杂环衍生物很难通过替代途径获得。
