Abstract

Propargyl thioimidates synthesized from readily-available starting materials are cyclized into non-aromatic dihydrothiazoles with high chemoselectivity using copper (I) iodide as a catalyst. These molecules engage in ene-type reactions with aldehyde, imine, and azo reacting partners with concomitant aromatization. A one-pot tandem hydroamination/ene process has been developed.
