Abstract
The protected cyclobutanone of the formula ##STR1## is treated with a dialkylaluminum chloride, an alkylaluminum dichloride, a trialkylaluminum compound, diphenylsilane in the presence of tris(triphenylphosphine) rhodium (I) chloride, or iridium tetrachloride to yield the corresponding diprotected cyclobutanol. This compound is useful as an intermediate in the preparation of antiviral agents.
