CuI-catalyzed coupling of 2-halotrifluoroacetanilides with L-proline or pipecolinic acid in DMSO at 90―110 °C followed by in situ hydrolysis at 100 °C afforded tetrahydropyrrolo[1,2-a]quinoxalines or tetrahydropyrido[1,2-a]quinoxalines.
CuI 催化 2-卤代三氟乙酰苯胺与 L-脯氨酸或哌可啉酸在 DMSO 中在 90-110 °C 下偶联,然后在 100 °C 下原位水解,得到四氢吡咯并[1,2-a]喹喔啉或四氢吡啶并[1,2-a] ]喹喔啉。
Synthesis of novel quinoxaline derivatives and its cytotoxic activities
copper-catalyzed coupling method. The reactions of 2-haloanilines with a variety of α-amino acids in the presence of copper (I) iodide gave corresponding 3-substituted dihydroquinozalin-2-ones in up to 86% yield. Some new quinoxalin-2-ones (2, 4, 5, 13 and 16) have moderate cytotoxic activity toward HeLaS3 cell lines at 4.9–18.1 μM.
