A catalyst free decarboxylative trichloromethylation of imines to afford different trichloromethyl sulfonyl and sulfinyl amines has been presented. Only DMSO as a solvent at room temperature was necessary to provide the corresponding products in good to high isolated yields. A highly diastereoselective version was carried out, leading to the sulfinylimine with good yield and near perfect diastereoselectivity
已经提出了亚胺的无催化剂的脱羧三氯甲基化以提供不同的三氯甲基磺酰基和亚磺酰基胺。在室温下仅需使用DMSO作为溶剂即可以高至高的分离收率提供相应的产品。进行了高度非对映选择性的反应,得到的亚磺酰亚胺具有良好的收率和接近完美的非对映选择性。关于反应曲线,采用ATR-FTIR光谱支持整个机理,并提供有关三氯乙酸盐对亲电试剂行为的分析以及在不同溶剂存在下的细节。
