The cleavage of C–N bonds is an interesting and challenging subject in modern organic synthesis. We have achieved the first zwitterion-controlled C–N bondcleavage in the MCR reaction among lithium alkynethiolates, bulky carbodiimides, and acid chlorides to construct N-acyl 2-aminothiazoles. This is a simple, highly efficient, and general method for the preparation of N-acyl 2-aminothiazoles with a
