  • Title: Catalytic asymmetric synthesis of axially chiral o-iodoanilides by phase-transfer catalyzed alkylations.
    Author: Shirakawa S, Liu K, Maruoka K.
    Journal: J Am Chem Soc; 2012 Jan 18; 134(2):916-9. PubMed ID: 22208662.
    Abstract:
    Catalytic asymmetric synthesis of axially chiral o-iodoacrylanilides and N-allyl-o-iodoanilides as useful chiral building blocks was achieved via chiral quaternary ammonium salt-catalyzed N-alkylations under phase-transfer conditions. The transition-state structure for the present reaction is discussed on the basis of the X-ray crystal structure of ammonium anilide.
