An efficient I2-catalyzed synthesis of thiazolylidenes and 1,4-dithiines from β-ketothioamides (KTAs) has been developed by only controlling the amount of I2 that triggers different cascade reaction sequences by means of [3+2] or [3+3] cyclocondensation in a one-step process. A possible mechanistic proposal for these transformations is presented.
