positions) undergo reduction with zeolite H-ZSM 5/NaCNBH3 combination of reagent system in refluxing dichloroethane to give 1,2-diols and homoallylic alcohols in moderate to good yields. Under these conditions acid sensitive groups such as an acetal and a THP ether are not affected which indicates the mildness of the reaction conditions.
