Circular dichroism evidence for a stereospecific complexation reaction in copper(II) chelates of poly-α-amino-acid ligands
Abstract
Evidence is presented for the stereospecific formation of the CuII derivatives of NN′-bis(salicylaldiminato) poly-L-ornithine and poly-L-lysine where the two diastereotopic faces of the square planar metal chelates are alternately bridged to the α-helical polypeptide matrix.
