The reaction of 3-chloro-2-(chloromethyl)-1-propene(1) with lithium and a catalytic amount of naphthalene in the presence of different carbonyl compounds in THF a -78 degrees C affords, after hydrolysis, the corresponding methylenic diols 2, which by a tandem hydroboration-oxidation with hydrogen peroxide followed by treatment with PCC (for ketone derivatives) or RuCl2(PPh(3))(3) (for aldehyde derivatives) yields the expected perhydrofurofurans 3.
