(1R,5S)-(+)-nopinone of high enantiomeric purity

Article abstract of DOI:10.1080/00397919608003558

Commercial β-pinene of 87% ee can be upgraded to the 98+% ee level by simple treatment with silver perchlorate. A solid complex is obtained whose formation is more rapid when two like enantiomers are involved. Simple dissolution of this precipitate in water releases the enantio-enriched hydrocarbon from which (+)-nopinone of high enantiomeric purity is obtained via ozonolysis.
