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