title: Chiral acetals as stereoinductors: diastereoface selective alkylation of dihydrobenzoxazine-derived amide enolates
abstract: Novel dihydrobenzoxazine-derived acetals of type 3 have been developed for asymmetric C-alkylations of propionyl amide enolates. High stereoselectivities are obtained for amides 15 and 22 which are rationalized in terms of intramolecular metal chelate formation.
