Synthesis and reactions of polynuclear heterocycles: Azolothienopyrimidines and thienothiazolopyrimidines

We prepared a thieno[2,3-d]pyrimidine compound fused with a thiazolo ring to produce biologicaly active compounds. In a one-step reaction, 2-arylmethylene derivative (3) was prepared via the reaction of a ternary mixture of 2-thioxo-1,2,3,4-tetrahydrocycl
