Abstract

1503723 Cyclic alcohols SCM CORP 14 Oct 1975 42063/75 Heading C2C The invention comprises a process for hydrogenation, with elemental hydrogen gas in the presence of a hydrogenation catalyst, under hydrogenation conditions, of a cyclic unsaturated compound having a hydroxyl group projecting from an asymmetric centre of the ring and an olefinic carbon-to-carbon double bond which when saturated in the hydrogenation process creates an additional asymmetric centre in the ring, wherein for obtaining increased stereoselectivity by increasing the addition of said hydrogen to that side of the olefin bond on the same side of the compound molecule as said hydroxyl group, said hydrogenation is conducted with a nickel containing hydrogenation catalyst that has a substantial fraction of its reactive surfaces inactivated.
