We report a protocol for palladium‐catalyzed dearomatizing alkoxydiarylation of furan rings via aerobic oxidative coupling between arylboronic acids and 5‐aryl‐2‐hydroxyalkylfurans. This green protocol starting from furan derivatives, which can be sustainably sourced, provides rapid access to polysubstituted 2,3,3a,6a‐tetrahydrofuro[3,2‐b]furans and hexahydrofuro[3,2‐b]furans, oxabicyclic frameworks
我们报告了一种通过芳基硼酸和5-芳基-2-羟基烷基呋喃之间的好氧氧化偶合使呋喃环的钯催化脱芳香化烷氧基二芳基化的方案。此绿色协议从呋喃衍生物开始,可以持续采购,可快速使用多取代的2,3,3a,6a-四氢呋喃[3,2- b ]呋喃和六氢呋喃[3,2- b ]呋喃,氧杂双环框架被具有重要生物活性的各种天然产物和合成分子所共有。
