Synthesis, resolution and structure of axially chiral atropisomeric N-arylimides
摘要:
Reported is the synthesis and structures of a new series of axially chiral molecules based on restricted rotation. The ortho-substituted N-arylimides have enantiomeric atropisomers-that are stable and separable at room temperature. The compounds are notable for their ease of synthesis as well as positioning of functionality (a carboxylic acid and an amine) in a highly asymmetric configuration.
