The separation of the enantiomers of substituted spiro(cyclohexadiene-indolines) was performed by enantioselective liquid chromatography with the sorbent/solvent systems triacetylcellulose/methanol, triacetylcellulose/ethanol/water, and (+)-poly(trityl methacrylate)/SiO2/n-hexane/isopropanol. The interconversion barriers of the enantiomers were determined for a series of derivatives by thermal racemization. A mechanism for the thermal ring opening/ring closure is discussed in terms of the Woodward-Hoffmann rules.
