The results reported in this study provide a practical protocol for the construction, in one single step of synthetically important γ-lactones in good yields starting from α‐hydroxy cyclobutanone, H2O2 and several stabilized phosphonium ylides. Our synthetic strategy relies on a tandem Baeyer–Villiger oxidation/Wittig reaction/oxa-Michael addition.
                                    本研究报告的结果提供了一种实用的构建方案,从 α-羟基
环丁酮、H 2 O 2和几种稳定的叶立德开始,一步合成重要的 γ-内酯,收率高。我们的合成策略依赖于串联的 Baeyer-Villiger 氧化/Wittig 反应/oxa-Michael 加成。
