A novel facile synthetic method for thienopyridine derivatives was proposed via the reaction of 2-amino-thiophenes with acetoacetic ester and tin tetrachloride under heating. A series of new 2-(amino/ acetoxy)-3-(4-methylphenyl)-thieno[3,2:5,6]pyrido[4,3-d]pyrimidin-4(3H)-one derivatives had been designed and synthesized via an aza-Wittig reaction and structually confirmed by IR, 1H NMR, EI-MS techniques, and elemental analysis. Their biological activities were also re-searched and many of them showed fungicidal activities against Fusarium oxysporium, Rhizoctonia solani, Gibberella zeae, Dothiorella gregaria and Colletotrichum gossypii to some extent. They exhibited 31.80%~82.84% inhibition against Dothiorella gregaria at 5.0×10-5 g/mL.

Key words: acetoacetic ester, aza-Wittig reaction, thienopyridine, pyrido[4,3-d]pyrimidine, fungicidal activity
