Syntheses and Transformations of 2,6-Epoxy-4H-3-benzoxocin-4-ones
Four variations for the preparation of 5 are described: acid-catalyzed cyclisation of the methoxy acid 4a, base-catalyzed lactonisation of the hydroxy ester 6b, DCC-mediated dehydration of the hydroxy acid 6a and PCC oxidation of the hemiacetals 17a and 1

Synthetic Photochemistry. XVIII. A Sensitizer Dependence in the Photooxidation of Indene and Acenaphthylene. The Occurrence of cis-1,2-Glycol Formation in a Rose Bengal-sensitized Reaction
Upon Rose Bengal-sensitized photooxygenation, indene and acenaphthylene afforded substantial amounts of the expected cis-glycols by means of the reduction of the intermediate dioxetanes.The formerly proposed structure of one of the isomeric methoxy hydroperoxides was revised on the basis of the chemical and spectral evidence.
