权利人:UNIV FLORIDA
摘要:The subject invention relates to a process for the synthesis of highly active binary metal fluoride system for the fluorination of aromatic compounds. Fluorinated aromatic compounds are valuable synthons for the chemical synthesis of pharmaceutical drugs and novel polymers. Fluorobenzene is used to control carbon content in steel manufacturing, is an intermediate for pharmaceuticals, pesticides and other organic compounds. Fluorobenzene is typically produced by the reaction of aniline and sodium nitrite in the presence of hydrogen fluoride. The present invention relates to a process for the synthesis of highly active binary metal fluoride system consists of copper (II) fluoride and aluminum (III) fluoride for the fluorination of aromatic compounds in gas phase and recycling of the reagent, in situ, using O 2 and HF.

标题:Enzymatic method for synthesis of carbohydrates
发明人：NILSSON KURT
摘要:A synthetic method in which is included at least one process, which is characterized by that a glycosidase (EC 3.2) is used to catalyse a reaction between a partially protected galactose derivative, or a partially protected glucose derivative, and a glycosyl doner, which is an oligosaccharide or a monosaccharide glycoside, is described. The process is suitable for synthesis of carbohydrate derivatives or for synthesis of partially protected carbohydrate intermediates which are suitable for further synthesis e.g. of blood group determinants A and B, or other carbohydrates.

权利人:UNIV TALCA
摘要:Described herein is a new asymmetric synthesis of imines to obtain β-carboline derivatives useful as key intermediate compounds for the synthesis of phosphodiesterase inhibitors using a new process with palladium or ruthenium hydride and/or nickel boride to reduce chiral intermediates. The use of chloroformate chiral auxiliaries is further described for the reduction and asymmetric hydrogenation of imines to obtain β-carboline derivatives and intermediate compounds used in the preparation thereof.
