A straightforward synthesis of non-symmetrical 3,5-diamidobenzyl amines, ethers and sulfides starting from 3,5-dinitrobenzoic acid is reported. Functionalization of the benzylic position is only achieved after formation of the two amides, otherwise benzylic hydrogenolysis occurs during nitro group reduction.
据报道,以3,5-二硝基苯甲酸为原料,可以直接合成不对称的3,5-二酰胺基苄基胺,醚和硫化物。苄基位置的官能化仅在两种酰胺形成后才能实现,否则在硝基还原过程中发生苄基氢解。
