5-hydroxymethyl-gamma-lactones were constructed after hydrolysis. This strategy also differentiates terminally substituted alkenes and constitutes a potentially novel synthetic approach for the efficient synthesis toward velbanamine.
开发了一种“停止流动”策略,用于通过 PIFA 引发的环化对烯烃进行化学选择性双氧化。该方法针对仲二烯的去对称化反应,水解后构建了一系列取代的5-羟甲基-γ-内酯。该策略还区分了末端取代的烯烃,并构成了一种潜在的新颖合成方法,用于有效合成维巴纳胺。
