1. Preparation and evaluation of a cyclic acyl nitrone as a synthon for stereospecific α-amino acid synthesis
2. Enantioselective synthesis of .alpha.-amino acid derivatives via the stereoselective alkylation of a homochiral glycine enolate synthon
3. Synthesis of nitrones by methyltrioxorhenium catalyzed direct oxidation of secondary amines
4. Synthesis of Nitrones Using the Methyltrioxorhenium/Hydrogen Peroxide System
5. After our initial development work was completed, nitrone 2 was prepared by an alternative synthesis and several cycloaddition reactions were reported.
