摘要
The scope of the NHC-redox amidation has been expanded to include a variety of alpha,beta-unsaturated aldehydes, including alpha-fluoro alpha,beta-unsaturated aldehydes which give rise to enantioenriched alpha-fluoroamides in good to excellent yield and enantioselectivity (up to 97% ee). Enantioenriched amines may be elaborated to either diastereomer of the product in high diastereoselectivity (up to 99 : 1). Functionalization of the amide products to amines and fluorohydrins is also demonstrated with retention of enantioenrichment at the fluorine stereocenter.
