  Stereochemical and Skeletal Diversity Employing Pipecolate Ester Scaffolds

  摘要：

  [GRAPHICS]The stereocontrolled synthesis of pyridooxazinones by Mg(OTf)(2)-promoted epoxide ring-opening with use of chiral pipecolates as nucleophiles is described. Pyridooxazinone products derived from azido-epoxides can be further rearranged to seven-membered pyridodiazepinones by azide reduction. The sequence of functional group interconversions generates diversity through topological and stereochemical variation.
