NEW SYNTHESIS OF 5,10-DIOXYPHENAZINE-2-CARBOXYLIC ACID
摘要:
Phenazine di-N-oxides substituted in the 2-position by a carboxylic function were prepared in few steps from 4-amino-3-nitrobenzoic acid via the formation of methyl 5,10-dioxy-6,7,8,9-tetrahydrophenazine-2-carboxylate without purification of the intermediates.
