Enantioselective Synthesis of Novel Functionalised Prolines via [3 + 2] Cycloadditions of a Chiral Azomethine Ylid

Abstract
The chiral, stabilised azomethine ylid 2 derived from (S)-2-phenylglycinol underwent enantioselective [3 + 2] cycloaddition reactions with a variety of unactivated and monoactivated dipolarophiles. Cycloaddition products were successfully deprotected to give chiral, functionalised proline derivatives.
