A synthetic approach towards the structurally complex dimer, kingianin A is reported. The strategy involved a cascade of complexity generating reactions, inspired through biosynthetic speculation. A concise protecting group free synthesis of the proposed monomeric precursor pre-kingianin A has been achieved using a tandem Stille cross-coupling reaction and electrocyclisation process. However, preliminary studies of the key dimerisation reaction have been conducted, which indicate that the process is not spontaneous, raising questions as to the origin of this complex natural product.
报告了一种合成结构复杂的二聚体金吉安因A的方法。这一策略涉及一系列复杂性生成反应,灵感来自于生物合成的推测。通过串联Stille交叉偶联反应和电环化过程,成功实现了提出的单体前体前金吉安因A的简洁无保护基合成。然而,关键的二聚反应的初步研究表明,该过程并非自发进行,这引发了对这一复杂天然产物起源的质疑。
