Abstract: | The group selective reductive cleavage of benzylidene acetals derived from diols containing chains equipped with a central chirotopic, nonstereogenic carbon atom is reported. The stereochemistry that is obtained at the central carbon is suitable for application to the synthesis of members of the streptovaricin class of antibiotics. |
