Conversion of benzene and chlorobenzene into polyhydroxylated cyclohexane derivatives related to cyclophellitol

Reaction of the dienes 4-6 with diphenylketene gave the -adducts 7-9 and the -adducts 10-12, respectively.The -adduct 10 has been converted into the ester 14 and the tetraol 16; the latter compound is an isomer of cyclophellitol 17.

Reaction of Diphenylketene with some Cyclohexa-3,5-diene-1,2-cis-diol Derivatives: Conversion of Chlorobenzene into Optically Active 2-Oxabicycloocten-3-one

The dienes 11-15 react with diphenylketene to give mixtures of the corresponding -adducts 16-20 and -adducts 21-25: the isomers 19/24 were converted into the optically active lactone 26 in two steps.
