Synthesis of enantiomerically pure trans aziridine-2-carboxylates by diastereoselective Gabriel-Cromwell reaction

Benzyl aziridine-2-carboxylates have been obtained in high yield and selectivity by conjugate addition of ammonia to α,β-unsaturated chiral imides followed by treatment with lithium benzyloxide. A ring-expansion of the aziridine to an oxazoline allowed th
