Oxazolo[5,4-f]quinoxalines, thiazolo[5,4-f]quinoxalines and pyrazino[b,e]isatins were all obtained from 5-iodo-6-aminoquinoxalines. While the first two families were synthesized by nitrogen functionalization and subsequent copper-catalyzed cyclization, the latter was obtained by Sonogashira coupling, alkyne hydration, and oxidative cyclization. Most of the synthesized polycycles were evaluated in biological
恶唑啉[5,4- f ]喹喔啉,噻唑并[5,4- f ]喹喔啉和吡嗪并[ b,e ] isatins都是从5-碘-6-氨基喹喔啉中获得的。前两个族是通过氮官能化和随后的铜催化环化合成的,而后者是通过Sonogashira偶联,炔烃水合和氧化环化获得的。大多数合成的多环化合物在生物学测试中进行了评估。
