  Staudinger Ketene−Imine Cycloaddition, RCM Approach to Macrocrocyclic Bisazetidinones

  摘要：

  Application of Staudinger ketene-imine cycloaddition reaction to bis-o-allyloxyarylideneamines afforded the corresponding bisallyloxyazetidinones; as the cis-cis diastereomers, exclusively obtained as a mixture of cis-syn-cis and cis-anti-cis. RCM of the latter using Grubbs' catalysts afforded the corresponding macrocyclic bisazetidinones in good yields. The cis-anti-cis bisazetidinones are readily identified by H-1 NMR using Eu(hfC)(3) chiral shift reagent.
