the gracilioether family were synthesized in only three steps. The monocyclic products were further elaborated into advanced precursors to hippolachnin A and gracilioether E, respectively. Gracilioether F and the alleged structure for gracilioether I were also synthesized using a late‐stage C(sp3)–H thermo‐oxidation.
仅在三个步骤中合成了禾本科醚家族中的两个单环成员。将单环产物进一步精加工成分别为河马霉素A和
松香醚E的高级前体。还使用后期C(sp 3)–H热氧化合成了Gracilioether F和所谓的gracilioether I结构。
