    • While finishing this work, Helmchen and co-workers reported the synthesis of new oxazoline ligands of type 15, starting from the (1S,2S)-(+)-2-amino-1-phenyl-1,3-propanediol 3 and using the method involving formation of an amide, transformation of the OH group into a leaving group and ring closure. This procedure was not applicable to the preparation of our bis(oxazoline) ligands, see: Peer, M.; de Jong, J. C.; Kiefer, M.; Langer, T.; Rieck, H.; Schell, H.; Sennhenn, P.; Sprinz, J.; Steinhagen, H.; Wiese, B.; Helmchen, G. Tetrahedron 1996, 52, 7547. (matrix presented)

    • We suppose that in the case of the diether bis(oxazoline) ligands, the complexation with the Cu(I) resulted in the formation of two catalytic species A and B. (matrix presented)
