Exploring original approaches for the synthesis of therapeutic agents having a quinazoline part, we discovered that novel 3,4-dihydro-2H-pyrazino[2,1,-b]quinazolines (3) may be rapidly and easily obtained via the chemistry of 4,5-dichloro-1,2,3-dithiazolium chloride (1). Our synthetic approach of this reaction is described with the aim of obtaining a well-controlled access to this very rarely described
探索合成具有喹唑啉部分的治疗剂的原始方法,我们发现可以通过化学反应快速,轻松地获得新型3,4-二氢-2 H-吡嗪并[2,1,-b ]喹唑啉(3)。 4,5-二氯-1,2,3-二噻唑鎓盐(1)。描述了我们对该反应的合成方法,其目的是获得对这种很少描述的吡嗪并[2,1,-b ]喹唑啉骨架的良好控制通道。
