The first total synthesis of (+)-5-epi-eudesm-4(15)-ene-1β,6β-diol has been achieved in 12 steps starting from the known (-)-cis-piperitol and by using a chelation controlled glycolate enolate Ireland-Claisen rearrangement and an intramolecular nitrile oxide dipolar cycloaddition as key steps.
(+)-5-表-艾里醇-4(15)-烯-1β,6β-二醇的首次全合成是从已知的(-)-顺式-胡椒醇出发,经 12 步反应完成的,其中关键步骤包括螯合控制的丙二酸酯烯醇负离子的爱尔兰-克莱森重排和分子内腈氧化物的偶极环加成。
