Abstract
A new method for the synthesis of chiral azetidinones bearing a carbon -carbon bond at the 4-position is described. The preparation involves a stereoselective alkylation-reduction of a silylated 4-phenylsulfonyl azetidinone. The utility of this method was demonstrated by a formal total synthesis of loracarbef.
