orthoacylimine-derived chiral auxiliaries has been synthesized and tested in the nucleophilicaddition of organolithium reagents to imines. The precursors can be prepared by an aza-Wittig reaction between the corresponding orthoacyl azide and a variety of aldehydes in the presence of trialkylphosphines. The nucleophilicaddition of organolithium reagents led to the addition products in good yields
