Synthesis of some new tetrahydrobenzo[b] thiophene derivatives and tetrahydrobenzo-thienopyrimidine derivatives under microwave irradiation

2-Phenyl-5,6,7,8-tetrahydro-4H-benzothieno[2,3-d][1,3]oxazin-4-one (4) was reacted with either aliphatic or aromatic primary amines such as benzylamine, cyclohexylamine, p-toluidine, and=or p-anisidine to give carboxamide derivatives 5a-d, respectively. A
