The present invention provides processes for the production of chiral compounds in a stereoisomeric excess, the processes comprising: (i) contacting a first compound comprising an alkene or alkyne bond with a hydrometallating agent, wherein the first compound and the hydrometallating agent are contacted under conditions such that the first compound is hydrometallated by said hydrometallating agent; and (ii) contacting the hydrometallated first compound with a second compound comprising an allylic group, wherein the hydrometallated first compound and the second compound are contacted under conditions such that they undergo an asymmetric allylic alkylation reaction in which a carbon atom of the hydrometallated first compound binds to a carbon atom of said allylic group, forming a stereoisomeric excess of a compound having a chiral centre in an allylic position, said chiral centre being located at the carbon atom bound by said first compound, wherein said asymmetric allylic alkylation reaction is performed in the presence of a metal catalyst comprising a chiral ligand. In particular, the present invention provides processes for the production of a stereoisomeric excess of a compound of the formula (IA), (IB), (IA') or (IB') as defined herein.

The present invention relates to novel quaternized ammonium salts of hydrocarbyl epoxides, to the preparation thereof and to the use thereof as a fuel additive and lubricant additive, such as, more particularly, as a detergent additive; for reducing or preventing deposits in the injection systems of direct injection diesel engines, especially in common rail injection systems, for reducing the fuel consumption of direct injection diesel engines, especially of diesel engines with common rail injection systems, and for minimizing power loss in direct injection diesel engines, especially in diesel engines with common rail injection systems; and as an additive for gasoline fuels, especially for operation of DISI engines.
Methods for modifying therapeutic agents such as therapeutic biomolecules, such as proteins for improved oral, rectal or transmucosal delivery, as well as compositions made using such methods and methods of administering such compositions to a subject, are disclosed. Specifically, the therapeutic agents are conjugated to hyperbranched polymers (HBPs), such as hyperbranched polyglycerol (HPG). When such conjugates are administered orally to a subject, the HBP protects the therapeutic agent from the acid environment of the stomach and protease attack in the gastro-intestinal tract, while facilitating the absorption of the therapeutic agent in the higher pH environment of the intestines. The methods and compositions are useful for the improved administration of a variety of therapeutic agents to a subject.
