angular carbon-functionalised, highly substituted, isomerically pure (ds ≥ 98%) 2-oxabicyclo[3.3.0]octanes and 2-oxabicyclo[3.4.0]nonanes in high yields by a convenient one-pot sequence. Molecular frameworks such as these can be found in many biologically active natural products. In addition to the methodological work, we report on studies towards the total synthesis of the euglobals G1 and G2 and arenaran
2-环戊烯基-和2-环己烯基甲基亚砜亚胺可以转化为有角碳官能化、高度取代、异构纯(ds≥98%)的2-氧杂双环[3.3.0]辛烷和2-氧杂双环[3.4.0]壬烷。通过方便的一锅序列产生产量。诸如此类的分子框架可以在许多具有生物活性的天然产物中找到。除了方法论工作外,我们还报告了对 euglobals G1 和 G2 以及 arenaran A 的全合成的研究。
