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。

Rhodium(II) catalyzes carbene transfer from trimethylsilyldiazomethane to arylmethyl thioethers, generating sulfonium ylides that undergo [2,3]-sigmatropic rearrangement, punching quaternary centers into aromatic rings. The reaction works well with naphthalene, indole, and benzofuran ring systems, but the reaction is unsuccessful with the monocyclic benzene homologue. For aryl thioethers, Rh2(OAc)4
