Synthesis of original benzo[<i>g</i>]quinoxaline-5,10-diones by bis-S<sub>RN</sub>1 methodology
3-bis(chloromethyl)benzo[g]quinoxaline-5,10-dione, was prepared in a four-steps synthesis. It was shown to react under electron transfer conditions with 2-nitropropane anion by an bis-SRN1 mechanism to give three C-alkylation products in excellent yields. Extension of this bis-SRN1 reaction to various nitronate or malonate anions and S-centered anions led to a new class of potentially active benzo[g]quinoxaline-5
