Abstract

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) may be rapidly and easily obtained via the chemistry of 4, 5-dichloro-1, 2, 3-dithiazolium chloride). Our synthetic approach of this reaction is described with the aim of obtaining a well- controlled access to this very rarely described pyrazino [2, 1,-b] quinazoline skeleton.
