A possible biomimetic synthesis of pyridomacrolidin has been proposed and experimentally supported by carrying out a model study. Regio and stereospecific [3+2] cycloaddition of an in situ generated unusual di-tert-butylated acyl nitrone with Z-2-cyclodecenone and subsequent aromatisation was the key step in our proposed biomimetic synthesis. Finally a pyridomacrolidin analogue was prepared via Friedel–Crafts
已经提出了可能的仿生大黄素合成方法,并通过进行模型研究得到了实验支持。原位生成的不寻常的二叔丁基化酰基硝酮与Z -2-环癸烯酮的区域和立体特异性[3 + 2]环加成反应以及随后的芳构化是我们拟议的仿生合成的关键步骤。最后,通过环加合物的Friedel-Crafts二脱叔丁基化反应制备了一个嘧啶大环素类似物。
