[摘要]:Regioselective introduction of an (alpha-nitro)alkyl group to the 1-methyl-2-quinolone framework was performed upon treatment of 1-methyl-3,6,8-trinitro-2-quinolone with nitroalkanes in the presence of triethylamine, in which a nitronate anion attacks at the 4-position and the subsequent aromatization by elimination of nitrous acid lead to 4-(alpha-nitro)alkylated 6,8-dinitro-1-methyl-2-quinolones. |
