A novel straightforward and catalyst-free approach for synthesizing quinoxaline derivatives from sulfoxonium ylides and o-phenylenediamines mediated by elemental sulfur has been described. Due to the simple and mild reaction conditions, the sulfoxonium ylides and o-phenylenediamines decorated with different functional groups furnished moderate to high yields of quinoxaline derivatives and were well
描述了一种由硫叶立德和邻苯二胺以元素硫介导合成喹喔啉衍生物的简单且无催化剂的新方法。由于反应条件简单温和,不同官能团修饰的亚砜叶立德和邻苯二胺提供了中等到高产率的喹喔啉衍生物,并且具有良好的耐受性。最后,使用大规模反应、吡嗪的合成和一些生物活性化合物来说明所开发方法的潜在效用。
