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.
描述了合成在4-位带有碳-碳键的手性氮杂环丁酮的新方法。该制备涉及甲硅烷基化的4-苯基磺酰基氮杂环丁酮的立体选择性烷基化还原。正式的劳拉卡帕夫全合成方法证明了该方法的实用性。
