A hydrogenation catalyst, preferably palladium on a support, preferably alumina or activated charcoal support, is used in the presence of lithium salts, with salts such as the borates being preferred. This provides hydrogenation of precursors to give rise to a stereoselective, such as diastereoselective bias in the product of alkene hydrogenation using the catalyst.
