The naphthalene-catalysed lithiation of 3-chloro-2-(chloromethyl)prop-1-ene, in the presence of symmetrically substituted ketones, led to the corresponding methylenic homoallylic diols, which upon treatment with iodine and silver(I) oxide in dioxane/water furnished a series of 1,6-dioxaspiro[3.4]octanes. These compounds are structural units present in some natural compounds such as clementeins and subexpinnatins.
