Gorelik, R. Alimova, V. Shteiman, T. Gladysheva, V. Tafeenko, S. Medvedev] The reaction of N,N′-dialkyl- or N,N′-diaryl-1,5-diaminoanthrones with sulfur in a polar aprotic solvent in the presence of a base leads to the formation of 4-alkyl(aryl)amino-9-alky(aryl)-5H-anthra[1,9,8-bcde]-9-aza-1,10λ4-di-thiapentalen-5-ones. The reaction of the 1,5-diaminoanthrone, followed by methylation, leads to 7-amino-10-methylthio- and 7-amino-8,10-dimethylthio-6H-anthra[9,1-cd]isothiazol-6-ones. The structures of the last two compounds and of 4-methylamino-9-methylazadithiapentaleneanthrone were studied by x-ray crystallography. Elimination of the amino group occurs in each series. The structural features and the spectral characteristics of the new heterocyclic systems are discussed. Plenum Publishing Corporation, 1990 Gorelik M.
