Chemistry of Heterocyclic Compounds Aims and scope

Abstract

Treatment of 4-aryl-5-aminopyrazoles and 2-aryl-3-amino-maleimides with tris(morpholino)methane gives N-azolyl formamidines which are converted upon heating in trifluoroacetic acid to polycondensed heterocycles with isoquinoline and indolo[2,3-c]pyridine structural fragments.
