Synthesis of Tetrahydropyrrolo[1,2-a]quinoxalines and Tetrahydropyrido[1,2-a]quinoxalines via a One-Pot CuI-Catalyzed Aryl Amination-Hydrolysis-Condensation Process

[摘要]：CuI-catalyzed coupling of 2-halotrifluoroacetanilides with L-proline or pipecolinic acid in DMSO at 90-110 degrees C followed by in situ hydrolysis at 100 degrees C afforded tetrahydropyrrolo[1,2-a] quinoxalines or tetrahydropyrido[1,2-a] quinoxalines.
