diazomethane is (1R,2S,3R,4S,5S)-2,3,4-tribenzoyloxy-1-hydroxy-6-oxabicyclo [3.2.1]octane (15); small proportions of the epimeric spiro-epoxides and 1-acetyl-6-benzoyloxy-7-methoxy-1H-indazole are also formed. On photobromination, the acetate (17) of 15 undergoes substitution at C-7 and, from the product, C-formyl-deoxyinositol derivatives are produced.
