摘要：
Ethyl 4H‐pyran‐4‐one‐2‐carboxylate was allowed to react with 1,2‐diaminobenzene and related diamines. The resulting products were found to be 8H‐5,6‐dihydro‐6,8‐dioxopyrido[1,2‐a]quinoxaline and derivatives. The synthesis 3H‐5,6‐dihydrobenzo[g]pyrido[1,2‐a]quinoxaline‐3,5‐dione (2c) constitutes the synthesis of a derivative of previously unknown benzo[g]pyrido[1,2‐a]quinoxaline ring system.
