Treatment of trans- ethyl-3-phenyl glycidate with benzylamine gave alpha-hydroxy beta-amino ester 1, which was converted stereospecifically into trans-1-benzyl-2-ethoxycarbonyl-3-phenyl aziridine (2) via Mitsunobu reaction.
Abstract The scope and limitations of guanidiniumylide mediated aziridinations from arylaldehydes yielding unactivated 3-arylaziridine-2-carboxylates, applicable to asymmetric synthesis, are discussed.

stereochemistry of these compounds has been determined by spectroscopic methods. Further, greater diversity of β-lactams via ring expansion of these azridines-2-carboxylates were obtained by a general, efficient and direct stereospecific approach.
