主　　题：2 Ethynylanilines Cyclization reaction Indoles Water Potassium carbonate 

摘      要：The cyclization reaction of 2-ethynyl-N-sulfonylanilides proceeded efficiently in water with the presence of a catalytic amount of K2CO3 under transition metal-free condition to give indoles in high *** recovery and reusability of the present catalytic system were investigated.
