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.

Chelate-controlled diastereoselective hydrogenation with heterogeneous catalyst

A catalyst, method of using, and use of a hydrogenation catalyst, preferably palladium on a support, preferably alumina or activated charcoal support. This 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. This equation, using the preferred substrate, best illustrates the invention: 

A polymer comprising a bulk polymer or copolymer Ptogether with an amount of a polymer-dendron additive D-Pof formula (I): is provided, such that the polymer comprises from 0.001 to 50% of dendron-additive D-Pcalculated as weight of dendron D in polymers D-Pand P, wherein:
