Catalyst-Free Alkylation of Quinoxalines in Water

Key Points

• The method achieves efficient synthesis of C3-alkylated quinoxalin-2(1H)-ones without catalysts, indicating a significant advancement in organic chemistry.
• Markedly, the reaction's kinetics accelerate in water due to strong hydrogen-bonding effects that enhance reactant interaction and aggregation.
• Analysis adopts a catalyst-free approach, which selectively activates the imine moiety, diverging from traditional metal-dependent strategies.
• These findings highlight a promising alternative for synthesizing functionalized compounds, potentially easing synthetic processes in various applications.
