Photosensitized Oxidation of Furans. 20.1 A Novel Thermal Rearrangement of Suitably Substituted Alkoxyfuran Endoperoxides via Neighboring-Group Mechanism: Synthesis and Reactivity of the First Functionalized 2-Oxetanyl Hydroperoxides

“…Compounds 3 are the first examples of functionalized 2-oxetanyl hydroperoxides and, as exemplified by derivative 3a , exhibit interesting chemical properties. Indeed, treatment with an equimolecular amount of Et 2 S quantitatively and stereoselectively led to the Z -keto ester 4a , while acid-catalyzed hydrolysis gave, in fair yield, the 5-hydroperoxyfuran-2(5 H )-one 6a in addition to 4a (Scheme ) .…”
