Some new aldazino 4, pyrazolo 5, thieno 8, and thiooxopyrimidino chromenes 10 were prepared via reaction of the corresponding beta-chlorocarboxaldehyde 3 with hydrazine hydrate, mercaptoacetic acid, and thiourea, respectively. Wherever, 4-chlorochromene derivatives 2 along with 4-chlorochromen-3-carboxaldehyde derivatives 3 were prepared from the corresponding ketone 1 with Vilsmeier-Haack reagent. Some of the new products showed good anti-inflammatory, analgesic, anticonvulsant, and antiparkinsonian activities comparable to indomethacin, diclofenace, carbamazepine, and benztropine.
