An efficient one-pot process was developed to synthesize 4H-chromene derivatives using a three-component reaction involving salicylaldehydes, cyclic 1,3-diketones, and thiols in an aqueous medium at room temperature. This protocol was accomplished using the inexpensive and readily available catalyst NH4Cl. The attractive features of this protocol are: use of inexpensive catalyst NH4Cl, good yields, and mild and environmentally benign reaction conditions. Georg Thieme Verlag Stuttgart · New York.
