Herein, we present a developed method for two-step synthesis of quite underrepresented heterofused ε-sultams annelated on face [d]. An approach is based on the alkylation of N-monosubstituted methanesulfonamides with alkyl (hetaryl caboxylates) possessing vicinal chloro/bromomethyl group. Thus obtained alkyl 2-(methylsulfonamidomethyl)hetaryl carboxylates readily participate in the sulfa-Dieckmann
在此,我们提出了一种开发的方法,用于两步合成相当少见的异质融合 ε-sultams annelated on face [ d ]。一种方法是基于N-单取代的甲磺酰胺与具有邻位氯/溴甲基的烷基(杂芳基羧酸酯)的烷基化。由此获得的烷基 2-(甲基亚磺酰氨基甲基) 杂芳基羧酸盐很容易参与磺胺-Dieckmann 缩合,得到所需的杂融合 ε-磺胺。该方法显示出广泛的底物范围,而目标化合物显示出巨大的合成潜力。
