  In the absence of added dipolarophile, chiral stabilised azomethine ylids derived from the reaction of 5-(S)-phenylmorpholin-2-one (1) with aldehydes undergo efficient and highly enantiocontrolled cycloaddition with a second molecule of aldehyde to furnish products which may be converted into beta-hydroxy-alpha-amino acids.
