The total synthesis ofrutaecarpine and several analogues has been developed by using an azido reductive cyclization process starting from substituted azido benzoic acids. The intramolecular azido reductive cyclization step was performed with triphenylphosphine or Ni 2 B in HCl―MeOH (1 M) using microwave irradiation. This synthetic route is amenable for the generation of a library of quinazolinone compounds
已经通过使用从取代的叠氮基苯甲酸开始的叠氮基还原环化过程开发了芸香果芸香碱和几种类似物的全合成。分子内叠氮基还原环化步骤使用三苯基膦或 Ni 2 B 在 HCl-MeOH (1 M) 中使用微波辐射进行。该合成路线适用于生成喹唑啉酮化合物库。
