N-substituted pyrrole-2-carboxylates has been developed based upon 1,3-dipolar cycloaddition and a conventional hydrogenolysis. By using this method as the key step, total syntheses of natural alkaloids (−)-hanishin, (−)-longmide B, and (−)-longmide B methyl ester were accomplished in the highest overall yields, respectively.
基于1,3-偶极环加成和常规的氢解,已经开发了N-取代的吡咯-2-羧酸酯的新型制备方法。通过使用该方法作为关键步骤,分别以最高的总收率完成了天然生物碱(-)-hanishin,(-)-longmide B和(-)-longmide B甲酯的总合成。
