Herein we describe a general, mild, and scalable method for hydrodeoxygenation of
readily accessible tertiary alkyl oxalates by Zn/silane under Ni-catalyzed conditions.
The reduction
method is suitable for an array of structural motifs derived from tertiary alcohols
that bear diverse functional groups, including the synthesis of a key intermediate
en route to estrone.
