A new two-step synthesis of pyrrole-2-carboxylic acids, steps via 1,3 dipolar cycloaddition of azomethine ylides to nitro-styrenes and oxidation of the resulting pyrrolidines with alkaline hydrogen peroxide is described. The oxidation of cycloadducts 3 by the means of MnO2 under different conditions also has been examined.
描述了吡咯-2-羧酸的新的两步合成,其步骤是通过偶氮甲亚胺的1,3偶极环加成至硝基苯乙烯,以及用碱性过氧化氢氧化所得的吡咯烷。还已经研究了在不同条件下借助于MnO 2氧化环加合物3。
