摘要
芳基酯酰肼很容易在甲醇中与碘代二乙酸苯酯(PIDA)发生反应,生成相应的 α-二氮杂环戊烯酯,而且收率良好甚至极高(30 个实例)。这些条件在合成三唑并吡啶时也被证明是有效的。含有重氮化合物和乙酸的粗混合物也可以用低能量的蓝色 LED 光照射,然后用 AcOH 一锅插入原位生成的碳烯,以高产率得到相应的乙酸盐。
Metal-Free Oxidation of Acceptor–Donor Acylhydrazones into Diazo Compounds Using Phenyl Iododiacetate
Aryl-ester acylhydrazones readily react with phenyl iododiacetate (PIDA) in methanol to produce the corresponding α-diazoesters with good to excellent yields (30 examples). The conditions have also been proven to be efficient in the synthesis of triazolopyridines. The crude mixture containing the diazo compound and acetic acid was also irradiated with low-energy blue LED light for a subsequent one-pot insertion of the in situ-generated carbene with AcOH to afford the respective acetates in high yields.
