A simple, straightforward synthesis of thienothiophene fused pyrimidine derivatives has been developed by the heterocondensation of symmetric thieno[2,3-b]thiophene o-aminonitrile with carbonyl compounds under different catalytic conditions. Furthermore, a novel unsymmetric thiophthene skeleton compound was also obtained via the intramolecular cross-conversion of the Friedländer transformation and

A series of new thienopyrimidinone derivatives were synthesized via a novel, straightforward and efficient tandem cyclo condensation of o-aminothienonitrile 1 and carbonyl compounds 2 in different conditions. The synthesized four thienopyrimidinone skeletons were thieno[2,3-d]pyrimidinone 3, tert-hydroxythieno[2,3-d]pyrimidinone 4, symmetrical tetracycle thienothiophene-pyrimidone 5 and thienopyrimidine 6 respectively. Their plausible mechanisms were proposed. The properties of compound 5 were investigated.
