Sažetak
2H-chromenes 3 and 4 have been synthesized by reduction of the appropriate lactone with diisobutylaluminium hydride and subsequent O-alkylation of the resulting lactols. Separations or enrichments of enantiomers were achieved by liquid chromatography on triacetylcellulose and tribenzoylcellulose, (+)-3 and (-)-3 being separated almost completely, while an enrichment of the enantiomers of 4 was achieved by using the recycling procedure. The barriers for the interconversion of enantiomers of 3 and 4 were determined by thermal racemization of enantiomers.
