  Rotational features of carbon-nitrogen bonds in axially chiral o-tert-butyl anilides and related molecules. Potential substrates for the ‘prochiral auxiliary’ approach to asymmetric synthesis

  摘要：

  A new strategy for asymmetric induction termed the 'prochiral auxiliary' approach is introduced. Reactions of acylating agents with prochiral N-methyl-o-tert-butyl aniline provide anilides that are axially chiral by virtue of restricted rotation about the N-Ar bond, Rotamer populations about the amide bond (E/Z) were studied by H-1 NMR. Several pairs of enantiomeric o-tert-butyl anilides were separated by chiral chromatography and barriers about the N-Ar bond were measured by thermal racemization. Related o-(1-(trialkylsilyloxy)-1-methylethyl) anilides were also studied. (C) 1997 Published by Elsevier Science Ltd. All rights reserved.
