Several chiral mono- and disubstituted 9,10-dihydro-9,10-ethanoanthracenes have been prepared from the corresponding anthracenes.Most of them were separated into enantiomers by chromatography on cellulose triacetate (CTA) and their absolute chiralities established by chiroptical comparison (via their CD spectra) with key compounds of known configuration.From the laevorotatory 1,5-dibromo derivative 16 the dextrorotatory dideuterio hydrocarbon (+)(9S,10S)-20 was obtained.Complexation of 2,6-dimethyl 9,10-dihydro-9,10-ethanoanthracene (+)-25, obtained by enantioselective chromatography on CTA
