	abstract = {Photolysis of crystals of a carboxylic acid-containing N,N-dialkylarylglyoxylamide to which an optically pure ammonium ion (the ionic chiral auxiliary) has been attached through a salt bridge leads to a 91\% isolated yield of a beta -lactam in greater than 99\% enantiomeric excess. Suspension of the crystals in hexane allows the photoreaction to be carried out on a 500 mg scale, thus demonstrating the synthetic utility of the solid stare ionic chiral auxiliary approach to asymmetric synthesis.},
