, p. 5640 - 5644 (1999)
The efficient asymmetric hydrosilylation of ketones with a chiral titanocene catalyst has been realized. In this procedure, (R,R)-ethylenebis(tetrahydroindenyl) titanium difluoride (1) was used as the precatalyst, and alcohol additives were employed. Arom

Epoxides of formula STR1 having a cyclanic (1R) configuration, the group in position 2 being in a trans configuration and the epoxy group being in a cis configuration with respect to that in position 1 of the ring, and in which R represents a lower alkyl group and R1 represents a saturated or unsaturated, linear or branched hydrocarbon group having from 1 to 8 carbon atoms, are useful molecules for the preparation of very prized perfuming ingredients. A process for the preparation of the opoxides (I) is also described.
