RESUMO

By comparison of experimental and theoretical CD curves the absolute configurations of chromatographically baseline-separated enantiomers of new trefoil molecular knots could be determined. From the results of syntheses with differently substituted starting materials, conclusions can be drawn about the knot-formation mechanism.

Novel Amide-Based Molecular Knots: Complete Enantiomeric Separation, Chiroptical Properties, and Absolute Configuration We would like to thank Prof. F. V. Schurig for his advice regarding the separation of the enantiomers. The results reported here were, in part, presented in Chamonix (September 2000; W.L.) and in Vienna, Tsukuba, Kopenhagen, Bordeaux, and Strasbourg (October-December 2000; F.V.).
