    摘要: Epoxides containing hydroxy groups are rearranged enantioselectively using a chiral base to give allyl alcohols in high enantiomeric excess, e.g. ##STR1## If R.sup.3 .noteq.H, the reaction also has the effect of generating a chiral tetrasubstituted carbon atom.

    摘要: A novel derivative of (-)-6,6-dimethylbicyclo [3.1.1]ept-2-ene-2-ethanol (J. P. Bain, J. Am. Chem. Soc. 1946, vol. 68, page 638) is disclosed. The parent composition is marketed e.g. under the name nopol, v. The Aldrich-Europe Catalog Handbook of Fine Chemicals, item 3160-5 nopol 98% 128-50-7.The object of the present invention is the compound of formula (I): 4-(2-hydroxyethyl) -.alpha..alpha.dimethyl-5-hydroxy-3-cyclohexene-1-methanol, with the process for obtaining the same, which consists of the preparation of (-)-(6,6-dimethylbicyclo[3.1.1]ept-2-ene-2-ethanol epoxide, followed by hydration of the above compound. Finally, this invention comprises the pharmaceutical compositions containing the compound of formula (I) which have a mucosecretolytic pharmacological activity.
