发现了碘离子原位生成的次碘酸盐试剂的一种新的催化应用，首次成功地合成了双苯并稠合的螺缩酮核。氟被证明是强制性的螺缩酮化，这是第一个氟促进氧化环醚化芳香族螺缩酮。
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.
