A series of 3-substituted [1]benzothieno[3,2-d]pyrimidine derivatives has been synthesized as possible antileukemic agents by condensation of methyl 3-(ethoxymethylene)amino-2-benzothiophene carboxylate (II) with a variety of amines to afford the corresponding 3-aryl and 3-alkyl [I]benzothieno[3,2-d]pyrimidin-4(3H)-ones, Ill and IV, respectively. In addition, Mannich reactions of [I]benzothieno[3,2-d]pyrimidin-4(3H)-one (VIII) with formaldehyde and secondary amines gave the expected derivatives, IX. 3-Amino[I]benzothieno[3,2-d]-pyrimidin-4(3H)-one (VI) reacted with substituted aromatic aldehydes in the presence of boron trifluoride to yield the corresponding imines VII. 相似文献
