Conformational preference in aromatic amides bearing chiral ortho substituents: its origin and application to relayed stereocontrol.
Tertiary aromatic amides bearing stereogenic centres ortho to the amide group may adopt two diastereoisomeric conformations which interconvert slowly on the NMR timescale at ambient temperature, and are therefore detectable by NMR. Certain classes of stereogenic centre--particularly sulfoxides, ephe...
