  Chiral Acetals as Stereoinductors:  Diastereoface Selective Alkylation of Dihydrobenzoxazine-Derived Amide Enolates

  摘要：

  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.
