What is Synthesis and Structure of 2-Substituted Thieno[3′,2′:5,6]pyrido[4,3-d]pyrimidin-4(3H)-one Derivatives about?
## Abstract A series of new 2‐substituted 3‐(4‐chlorophenyl)‐5,8,9‐trimethylthieno[3′,2′: 5,6]pyrido[4,3‐__d__]pyrimidin‐4(3__H__)‐ones **8** were synthesized __via__ an aza‐__Wittig__ reaction. Phosphoranylideneamino derivatives **6a** or **6b** reacted with 4‐chlorophenyl isocyanate to give carbodiimide derivatives **7a** or **7b**, respectively, which were further treated with amines or phenols to give compounds **8** in the presence of a catalytic amount of EtONa or K~2~CO~3~. The structure of 2‐(4‐chlorophenoxy)‐3‐(4‐chlorophenyl)‐5,8,9‐trimethylthieno[3′,2′: 5,6]pyrido[4,3‐__d__]pyrimidin‐4(3__H__)‐one (**8j**) was comfirmed by X‐ray analysis.
