Remote conformational responses to enantiomeric excess in carboxylate-binding dynamic foldamers†
Abstract
A crystallographically characterised zinc(II)-capped foldamer can sense the enantiomeric excess of scalemic carboxylate solutions, including those produced by enantioselective organocatalysis, and can relay this input signal along the foldamer body to a remote glycinamide group, which then provides an NMR spectroscopic output.
