title: New fluoride-promoted hypoiodite-catalytic oxidative cycloetherification to aromatic spiroketals.
abstract: 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.
