摘要：
Asymmetric alpha-amination through an N-heterocyclic carbene (NHC)-catalyzed redox reaction of alpha-aroyloxyaldehydes with N-aryl-N-aroyldiazenes to form alpha-hydrazino esters with high enantioselectivity (up to 99% ee) is reported. The hydrazide products are readily converted into enantioenriched N-aryl amino esters through samarium(II) iodide mediated N-N bond cleavage.
