The enantiomers of 6-methoxy-3,3’,3’-trimethylspiro[2H-1-benzopyran-2,1’[2]oxaindan] were separated with the high-pressure liquid chromatography method. Their optical properties were studied experimentally and by quantum-chemical calculations. The absolute configurations of the compounds were determined by comparison of the measured and calculated CD spectra.
