    摘要: A process for upgrading to essentially 100% enantiomeric excess the optical purity of an organoborane intermediate represented by the formulae:
    wherein Icp is isopinocampheyl and R * is a unsubstituted or substituted, acyclic or cyclic alkyl having from 4 to 30 carbon atoms, comprising the steps of hydroborating cis- alkene, a trans-alkene or a tertiary-alkene with monoisopinocampheylborane or diisopinocampheylborane, obtaining a solid organoborane and recrystallizing the solid organoborane to obtain an enantiomeric excess of essentially 100% ee of said organoborane.

    摘要: The invention provides derivatives of bornane-3-spiro-­1′-cyclopentane with woody note scent useful as a base component in perfumery formulations which comprises those having a substituting group selected from a methoxyl, ethoxyl, formyloxyl and acetoxyl groups or two of substituting groups being either a hydroxyl group and a methyl group or a hydroxyl group and an ethyl group at the 2-position synthesized by any of the reactions of bornane-3-spiro-1′-cyclopentan-2-ol or bornane-3-spiro-1′-cyclopentan-2-one with any of the reagents selected in accordance with the substituting group(s) to be introduced.
    The invention also provides perfumery compositions containing the above.
