A Facile One-Pot Procedure for the Synthesis of 1,2-Benzisothiazole 1,1-Dioxides ortho-Lithiated N,N-diphenylbenzenesulfonamides 6 react with aromatic nitriles and N,N-dimethylcarbamonitrile, respectively, to give directly the corresponding 3-substituted 1,2-benzisothiazole-1,1-dioxides 8a-f. Other cyano compounds only transfer the cyano group or its ligands to generate the o-substituted benzenesulfonamides 9a-d.
一种简便的一锅法用于合成1,2-苯异噻唑-1,1-二氧化物。正位锂化的N,N-二苯基苯磺酰胺6与芳香腈和N,N-二甲基氰脲酸酯反应,直接生成相应的3取代1,2-苯异噻唑-1,1-二氧化物8a-f。其他氰化合物仅转移氰基或其配体,生成o-取代苯磺酰胺9a-d。
