| Abstract: | It was shown that 2-(4-alkylpiperazino)-3-chloro-1,4-naphthoquinones react on heating with NaN3 in DMF to form new heterocyclic quinones — 1,2,3,4-tetrahydro-13-alkyl-3,1-(iminoethano)benzog]quinoxaline-5,10-diones as well as the corresponding 2-(4-alkylpiperazino)-3-aminonaphthoquinones and naphthimidazopyrazinediones.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 2103–2107, September, 1990. |
