Enantioselective recognition of histidine and lysine esters by porphyrin chiral clefts and detection of amino acid conformations in the bound state

Maxwell J. Crossley,  Lindsey G. Mackay  and  Andrew C. Try 

Abstract

Resolution of the bisporphyrin Tröger's base analogue 1 affords homochiral clefts that tightly bind histidine esters in 80–86% e.e. and lysine benzyl ester in 48% e.e.; the histidine esters are bound in fixed conformations that can be readily detected by 1H NMR spectroscopy as a result of the large dispersion of proton resonances by the ring currents of the two porphyrins.
