[reaction: see text]. Several approaches to asymmetricinduction in the alpha-oxoamide (1) to beta-lactam (2) photorearrangement are described. Best results are obtained via irradiation of ionic and covalent chiral auxiliary-containing reactants in the crystallinestate and in the interior supercages of zeolites.
