A Zn(OTf)2-catalyzed Mannich-typereaction of the electron-deficient aromatic amines with the electron-deficient aromatic aldehydes and diethyl malonic ester was described. This three-component reaction afforded the corresponding β-amino esters in good yields.

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.
