Abstract

New polyheterocyclic ensembles of 8,9,10,11-tetrahydro-7-thia-1,4,6,8-tetraazabenzo[de]anthracenes were prepared by reaction of easily available 5Н-pyrido[2’,3’:2,3]thiopyrano[4,5-b]pyridines with Ас2О or acyl chlorides. The starting 5Н-pyrido[2’,3’:2,3]thiopyrano[4,5-b]pyridines were prepared by reaction of N-methylmorpholinium 4-aryl-3-cyano-6-oxo-1,4,5,6-tetrahydropyridine-2-thiolates with malononitrile dimer.
