The dimer of methyl vinyl ketone, when treated with phenylmagnesium bromide, was converted to the exo and endo isomers of 7-phenyl-5,7-dimethyl-6,8-dioxabicyclo[3.2.1]octane. The x-ray crystallographic examination of the exo isomer provides the first detailed structural data for this interesting bicyclic ketal series. The method of synthesis and the x-ray structural data are provided.
