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.
