Design and synthesis of imidazolinium salts derived from (<scp>l</scp>)-valine. Investigation of their potential in chiral molecular recognition

Abstract

Several imidazolinium salts are synthesized from (L)-valine. A study of the structure relationships is achieved to obtain high diastereomeric interactions with an anionic substrate. High splitting up to 60 Hz of the (rac)-potassium Mosher's salt are observed by NMR spectroscopy.
