Synthesis of 4-Imino-2H,3H,5H-[1,2,5]thiadiazolidin-1-oxide through Cycloaddition Reaction of N-Sulphinylanilines and N-(α-Cyano-α-aryl)-methylanilines
摘要:
Through the normal mode of cycloaddition reaction of N‐(α‐cyano‐α‐aryl)‐methylanilines (II) onto N‐sulphinylanilines (III) has provided 2,3,5‐triaryl‐4‐imino‐2H,3H,5H‐[1,2,5]thiadiazolidin‐1‐oxides (IV). The present protocol has advantage of convenient operation to synthesize heterocyclics in good yield.

A straightforward, mild, efficient, one-pot method has been found for the synthesis of α-aminonitriles via three-component Strecker reaction using acetals or cyclic acetals, curious aromatic amines and trimethylsilyl cyanide (TMSCN) catalysed by hafnium tetrachloride at room temperature. It is with good to excellent yields under mild conditions. This developed approach has been successfully applied

A simple and efficient method has been developed for the synthesis of α-aminonitriles by a one-pot three-component condensation of aldehydes, amines, and trimethylsilyl cyanide in the presence of a catalytic amount of silicasulfuricacid at room temperature. The silicasulfuricacid is reusable and could be applied in subsequent reactions with comparable activity.
