and novel strategies for the synthesis of thienopyrimidines starting from 2-amino-3-carboethoxy-4,5,6,7-tetrahydrobenzo[b]thiophene has been developed. The regioselectivity of these synthetic strategies was investigated using density functional theory computation and spectroscopic analysis. In addition, the chemical structures of the new thienopyrimidines and their reaction mechanisms, as well as the

3-d]pyrimidin-4(4H)-one 1 (1), chloroacetic acid, and a proper aldehyde. Compound 2a react with hydroxyl amine hydrochloride to give corresponding oximederivative 4. Reaction of 1 with 3-chloropent-2, 4-dione in ethanolic sodium hydroxide solution yielded S-acetyl acetone derivative 5b. The latter compound reacted with hydrazines affording the 2-pyrazolthio 6. Compound 5b reacted with urea and thiourea to give 7a
