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

FUNCTIONAL DERIVATIVES OF THIOPHENE. 18. SYNTHESIS OF 4-OXOTHIENOOXAZINE DERIVATIVES AND THIOPHENE-3-CARBOXYLIC ACID HYDRAZIDES

2-Aryl-4-oxothienooxazine derivatives were synthesized.Opening of the oxazine ring to give 2-benzamidothiophene-3-carboxylic acid hydrazide derivatives is observed when these compounds are treated with hydrazine hydrate.
