Various synthetic routes to imidazothienopyrimidines and pyrimidothienopyrimidines in some cases annelated

The tricyclic or tetracyclic imidazothienopyrimidines and pyrimidothienopyrimidines were synthesized by three routes: Route A: Thieno1,3-thiazin-4-thiones E undergo the ring transformation with α,ω-diamino-alkanes to giv
