Abstract: Optically active organic compounds are prepared starting from optically inactive reactants by means of an optically active agent which influences the course of the reaction. In particular optically active compounds having a "meso" type carbon atom undergo an intramolecular ring closure in the presence of an optically active agent to yield an optically active product having one additional ring. The present process is particularly useful in the preparation of optically active bicyclic diketones which are important intermediates in the total synthesis of steroids.

Abstract: 1456830 Halogen-substituted undecanes F HOFFMANN-LA ROCHE & CO AG 21 Dec 1973 [22 Dec 1972] 22272/75 Divided out of 1456828 Heading C2C The invention comprises novel halides of general formula wherein X represents a halogen atom. They may be prepared by the halogenation of 2,6,10-trimethylundecan-1-ol. The latter compound may be prepared by dehydrating 7R,11R-phytol, treating the resulting product with ozone gas to form various ozonides, followed by reduction with a complex metal hydride to give a mixture of the above compound and 3,7,11-trimethylundecan-1-ol which may be separated by fractional distillation.
