标 题 :Supported highly-polar liquid phase chiral sulfonated binap catalyst for asymmetric synthesis of optically active compounds
发明人：DAVIS MARK E; WAN KAM TO
权利人:CALIFORNIA INST OF TECHN
摘要:The present invention relates to water soluble chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl and its use as organometallic catalysts for asymmetric synthesis of optically active compounds. Asymmetric reactions of the present invention include those reactions in which organometallic catalysts are commonly used. Such reactions include, but are not limited to, reduction and isomerization reactions on unsaturated substrates and carbon--carbon bond forming reactions. Examples of such reactions include, but are not limited to, hydrogenation, hydroboration, hydrosilylation, hydride reduction, hydroformylation, alkylation, allylic alkylation, arylation, alkenylation, epoxidation, hydrocyanation, disilylation, cyclization and isomerization reactions. n The catalysts of the present invention provide the advantage of functioning in the presence of water without loss in enantioselectivity relative to the nonsulfonated BINAP catalyst in an organic solvent. As a result, the catalysts of the present invention may be employed in water, water miscible solvents, in aqueous--organic two phase solvent systems and in supported aqueous phase catalysts in organic solvents without loss in enantioselectivity. Further, the catalysts of the present invention may also be effectively employed in highly polar solvents such as primary alcohols and ethylene glycol. n The present invention also relates to a method for conducting asymmetric reactions on prochiral unsaturated bonds contained within a compound using the water soluble chiral sulfonated 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl organometallic catalysts of the present invention.

标 题:Enzymatic synthesis of isotopically labeled carbohydrates
发明人：GOUX WARREN J
权利人:UNIV TEXAS
摘要:The present invention relates to a general method of enzymatic synthesis of isotopically labeled carbohydrates, sugars and nucleosides. Labeled citric acid cycle intermediates, amino acids and ribose mononucleotides may be rapidly and conveniently synthesized from labeled pyruvate, lactate or L-alanine. The method employs a novel nicotinamide dinucleotide regeneration system which permits use of low NADH levels. The method may be manipulated to allow labeling at a variety of carbon/hydrogen sites.

标题:Asymmetric synthesis catalyzed by transition metal complexes with rigid chiral ligands
发明人：ZHANG XUMU
权利人:PENN STATE RES FOUND
摘要:This invention is to develop novel transition metal catalysts for the practical synthesis of important chiral molecules. The invention emphasizes asymmetric catalysis based on chiral bidentate phosphine ligands with cyclic ring structures which could be used to restrict conformational flexibility of the ligands and thus the efficiency of chiral transfer can be enhanced through the ligand rigidity.

标题 :Method for preparing a bimetallic ruthenium/tin catalyst and a process for the synthesis of aldehydes
发明人：JACQUOT ROLAND
权利人:RHODIA CHIMIE SA
摘要:The present invention relates to a new process for the preparation of a bimetallic ruthenium/tin catalyst. The process for the preparation of a bimetallic ruthenium/tin catalyst according to the invention is characterised by the fact that it consists in carrying out the reduction of a ruthenium complex having an electrovalency of -4 and a coordination number of 6, the ligands being either a halogen atom or an anion or a tin halide. The catalyst is further employed for the preparation of aldehydes by reduction, in the vapor phase, of carboxylic acids, esters and anhydrides.
