Abstract
A facile and highly efficient copper‐catalyzed strategy has been developed for the synthesis of pyrrolo[1,2‐a]quinoxalines from 1‐(2‐aminophenyl)‐pyrroles and aldehydes at room temperature. This reaction proceeds via imine formation, cyclisation, and oxidation in one‐pot. This strategy provides a facile and rapid access to pyrrolo[1,2‐a]quinoxalines in good to high yields under mild conditions. This process has several advantages, such as simple reaction procedure, readily available starting materials, low catalyst loading, easy product isolation, broad substrate scope, high functional group tolerance, and gram‐scale synthesis.
