Abstract

Novel thiazolo [3,2-a]pyridine and thiazolo[3,2-a]pyrimidine derivatives, pyrazolo[3,4-b]pyrano[2,3-d]thiazole, and coumarin derivatives were synthesized from readily obtainable starting materials such as (Z)-2-ethoxycarbonyl methyl-5-(4-chlorobenzylidene)-2-thiazolidin-4(H)one 3 and (Z)-4-(4-hydroxybenzylidene)-2-imino-2-thiazolidin-4(H)one 11.
