Abstract: Generally, the present invention relates to the field of steroid hydroxylation. More specifically, the present invention relates to a method for the 21-hydroxylation of steroids in cells. It also relates to cells expressing a steroid 21-hydroxylating enzyme or steroid 21-hydroxylase, expression vectors comprising a nucleic acid encoding for a steroid 21-hydroxylase and a kit for carrying out the method for the 21-hydroxylation of steroids in cells.

Abstract: A process for preparing methionine includes the alkaline hydrolysis of 5-(2-methylmercaptoethyl)-hydantoin (methionine hydantoin) in an aqueous process solution containing alkali metal hydroxide and/or alkali metal carbonate and/or alkali metal hydrogencarbonate. The alkali metal cations in the process solution are potassium and sodium having a K/Na molar ratio range from 99/1 to 20/80.

Abstract: A process is used for preparing methionine. Specifically, the process includes the hydrolysis of 5-(2-methylmercaptoethyl)hydantoin (methionine hydantoin) in an alkaline process solution. Further, the by-products that include formate and other anions of organic acids containing 1 to 5 carbon atoms are removed by electrodialysis of the process solution.

Abstract: Processes for making an organozinc reagents are disclosed comprising reacting (A) organomagnesium or organozinc complexes with (B) at least one coordination compound comprising one or more carboxylate groups and/or alcoholate groups and/or tertiary amine groups, optionally in combination with zinc ions and/or lithium ions and/or halide ions, wherein the halide ions are selected from chloride, bromide and iodide, the organozinc complex comprises an aryl group, a heteroaryl group or a benzyl group when the coordinating compound is a chelating polyamine, and the reaction is conducted in the presence of zinc complexed with at least one coordinating compound when reactant (A) comprises at least one organomagnesium complex. The resulting organozinc reagents may optionally be isolated from solvents to obtain a solid reagent. The reagents may be used for making organic compounds via Negishi cross-coupling reactions or via aldehyde and/or ketone oxidative addition reactions.
