Reaction of 2-(4-alkylpiperazino)-3-chloro-1,4-naphthoquinones with sodium azide
摘要:
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)benzo[g]quinoxaline-5,10-diones as well as the corresponding 2-(4-alkylpiperazino)-3-aminonaphthoquinones and naphthimidazopyrazinediones.
Synthesis of photoactive 1-methyl-1-R-4-(1,4-dioxo-1,4-dihydronaphthalen-2-yl)piperazinium salts
摘要:
Photoactive 4-(1,4-dioxo-1,4-dihydronaphthalen-2-yl)piperazinium salts were synthesized by alkylation of 3-chloro-2-(piperazin-1-yl)-and 2-arylamino-3-(4-methylpiperazin-1-yl)-1,4-naphthoquinones. Light sensitivities of materials obtained by adsorption of the synthesized piperazinium salts from solution onto oxidized aluminum support were estimated.
