The 2,3-substituted pyrroles (4) have been prepared by a general method by cyclization in cold ethereal HCl of the methylthio-amino-vinyl compounds (3), which were obtained by condensation of the keten dithioacetals (1) with 2,2-diethoxyethylamine (2).
2,3-取代的吡咯(4)是通过在冷醚盐酸中环化甲硫基-氨基-乙烯基化合物(3)的常规方法制备的,所述甲硫基-氨基-乙烯基化合物(3)是通过将缩酮二硫缩醛(1)与2缩合而获得的。 2-二乙氧基乙胺(2)。
