Abstract
[reaction: see text]. A novel regioselective route for the synthesis of substituted and fused 3-chloro-2-(methylthio)quinoxalines through POCl3-mediated heteroannulation of a range of alpha-nitroketene N,S-anilinoacetals has been reported.
摘要
[反应：见正文]。据报道，通过三氯氧磷介导一系列α-硝基乙烯酮N,S-苯胺缩醛的杂环化反应，可实现一种新颖的区域选择性合成取代和稠合3-氯-2-(甲硫基)喹喔啉的路线。
