An operationally simple and efficient strategy for the synthesis of substituted tetrahydrofurans from readily available cis-butene-1,4-diol is described. A redox-relay Heck reaction is used to rapidly access cyclic hemiacetals that can be directly reduced to afford the corresponding 3-aryl tetrahydrofuran. Furthermore, the hemiacetals can also serve as precursors to a range of disubstituted tetrahydrofurans
描述了一种操作简单且有效的策略,用于从现成的顺式-丁烯-1,4-二醇合成取代的四氢呋喃。氧化还原中继 Heck 反应用于快速获得可直接还原以提供相应的 3-芳基四氢呋喃的环状半缩醛。此外,半缩醛还可以作为一系列二取代四氢呋喃的前体,包括花萼天然产物。
