A homochiral tripodal receptor with selectivity for sodium (R)-2-aminopropionate over sodium (S)-2-aminopropionate

This paper describes the synthesis and use of a homochiral tripodal imidazolium salt that can distinguish between sodium (R)-2-aminopropionate and sodium (S)-2-aminopropionate. The imidazolium salt complexes with the (R) enantiomer but not with the (S) enantiomer.
