Aryl gem-disubstituted conjugated alkenols underwent oxidative cyclization affording 2,5,5-trisubstituted tetrahydrofurans in reasonable yields and good diastereoselectivities using the reductive termination variation of the Mukaiyama aerobic oxidative reaction. Under oxidative termination, the same alkenols produced diols and ketonic by-products via the double hydration and beta-scission competing
使用Mukaiyama有氧氧化反应的还原终止反应,芳基宝石-二取代共轭链烯经过氧化环化,以合理的收率和良好的非对映选择性提供了2,5,5-三取代的四氢呋喃。在氧化终止作用下,相同的烯醇通过双重水合和β-断裂竞争途径产生二醇和酮副产物。此外,研究了在还原和氧化终止条件下烯醇反应性的差异。
