The bidentate complexes of (R,R)- and meso-α,α′-bis(trifluoromethyl)-9,10-anthracenedimethanol with cis-1-amino-2-indanol

The enantiorecognition of 1-aminoindane 3 and cis-1-amino-2-indanol 2 by (R,R)-α,α′-bis(trifluoromethyl)-9,10-anthracenedimethanol 1 is reported. The examination of the bidentate associations between 1 and 2 revealed that the cisoid conformation of 1 is responsible for the separation of the NMR signals. Two types of bimodal associations resulted from a cisoid conformation when meso-1 isomer was tested. Molecular mechanics modelling studies gave the possible structures of the associate species.
