5-Imino-1,2,4-thiadiazolidin-3-ones 1 react with compounds alkylidene-1,2,4-dithiazolidines 12 are formed. The reaction products with enamines undergo hydrolysis and elimination containing electron-rich double bonds such as enamines and ester enolates to afford the 2-iminothiazolidines 3, 4, and 10
