Description

3-Methyl-2-quinoxalinone is a heterocyclic compound featuring a fused quinoxaline core with a methyl group at the 3-position. This electron-deficient scaffold enables efficient coupling in transition metal-catalyzed reactions and serves as a robust building block in medicinal chemistry. The structure exhibits enhanced stability under standard bench conditions, facilitating direct incorporation into complex molecular architectures.

Application

3-Methyl-2-quinoxalinone serves as a versatile building block in medicinal chemistry, enabling efficient access to quinoxaline-based scaffolds through standard coupling and functionalization reactions. Its inherent stability, combined with moderate reactivity at the C3 position, facilitates straightforward derivatization for target-oriented synthesis. The molecule functions effectively in transition-metal-catalyzed cross-couplings and serves as a key intermediate in the development of heterocyclic compounds with defined pharmacophores.
