The reaction of nitroalkanes with trimethyl trans-aconitate in acetonitrile, in the presence of DBU as base, allows the one pot formation of alkylated methyl tri- and tetralkanoate derivatives via base induced nitrous acid elimination. The title compounds can also be obtained, in one flask, starting with the reaction of methyl nitroacetate with dimethyl maleate, followed by the addition, in the same flask of the nitroalkane.
在含有DBU作为碱的乙腈中,硝基烷与三甲基反式乙烯酸酯的反应允许通过碱诱导亚硝酸的消除,一锅合成烷基化的甲基三烷酸酯和四烷酸酯衍生物。这些标题化合物也可以通过在同一反应瓶中,首先使甲基硝基乙酸酯与二甲基马来酸酯反应,然后加入硝基烷来获得。
