A new catalytic application of hypoiodite reagents generated in situ from iodide ions is found, which succeeded in the synthesis of bisbenzannelated spiroketal cores for the first time. Fluoride was proven to be obligatory for this spiroketalization, which is the first fluoride-promoted oxidative cycloetherification to aromatic spiroketals.
发现了碘离子原位生成的次碘酸盐试剂的新催化应用,首次成功合成了双苯并螺缩酮核。氟化物被证明对于这种螺缩酮化反应是必需的,这是第一个氟化物促进的芳香族螺缩酮氧化环醚化反应。
