4-Chloro-2,2-disubstituted chromen-3-carboxaldehyde: synthesis of some fused polycyclic heterocycles as anti-inflammatory, analgesic, anticonvulsant, and antiparkinsonian agents.

Abstract

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… (More)
