Stereospecific synthesis of chiral N-(ethynyl)allylglycines and their use in highly stereoselective intramolecular Pauson-Khand reactions

The first synthesis of an enantiopure N-ethynylated allylglycine and its application in the intramolecular Pauson-Khand reaction, which leads to a novel highly functionalised proline derivative with complete control of stereoselectivity, is reported.
