(2R)-N-Boc-4-oxo-proline was used as a reactant in the preparation of 4,4-disubstituted pyrrolidine-1,2-dicarboxamides which are potent factor Xa inhibitors with increased human half life. Also used in the synthesis of azacyclic FTY720 analogues which show potential for use in strategy to kill cancer cells as they restrict access to extracellular nutrients.
