                                    Chiral, stabilised azomethine ylids incorporated in cyclic templates derived from (R)- or (S)-2-phenylglycinol and (S)-valine undergo enantioselective 1,3-dipolar cycloaddition reactions with a variety of dipolarophiles.  Removal of the template in the case of adducts derived originally from (S)-valine furnishes enantiomerically pure alpha-substituted proline derivatives.
