New Routes to Regioselectively Mono-Protected 1,3-Diols from Allyl and Homoallyl Alcohols via Intramolecular Hydrosilation

Abstract Allyl and homoallyl alcohols are transformed into 1,3-diol derivatives, in which only the originally present hydroxy groups are regioselectively protected, by a sequence of intramolecular hydrosilation, protection, and oxidative cleavage of the carbon–silicon bond. Stereochemical aspects are also described.
