Utilization of Amberlyst-A21 without solvent in the conjugate addition of nitroalkenes to methyl acrylate, affords 4-nitroalkanoic methyl esters in good yields. Successive Nef reaction, using potassium permanganate, provides functionalized 4-oxoalkanoic methyl esters.
在没有溶剂的情况下,使用Amberlyst-A21对亚硝基烯烃进行共轭加成到丙烯酸甲酯,可以获得良产率的4-硝基烷酸甲酯。随后使用高锰酸钾进行Nef反应,可以得到功能化的4-氧烷酸甲酯。
