efficient one-pot method for the synthesis of 2-aminothiazoles using simple starting materials like isothiocyanates, amidines/guanidines and various halomethylenes is reported. The synthesis of 2-aminothiazoles involves reactions such as nucleophilic addition, S-alkylation and intramolecular nucleophilic substitution in which amines departs as the leaving group.
报道了一种有效的一锅法,该方法使用诸如异硫氰酸酯,am /胍和各种卤代亚甲基之类的简单原料来合成2-氨基噻唑。2-氨基噻唑的合成涉及诸如亲核加成,S-烷基化和分子内亲核取代的反应,其中胺作为离去基团离开。
