标 题:Novel synthesis of methyl-2-fluoroacrylate
发明人：BRUNKE JESSICA; FISCHER MICHAEL; WÖSSNER JAN STEPHAN
权利人:VIFOR INT AG
摘要:The present invention relates to novel synthesis methods of methyl 2-fluoroacrylate (MFA) which is a key precursor for the production of Veltassa® (Patiromer). The methods according to the invention are conducted by reacting an α-substituted β-hydroxy propionic acid derivative (I) via one or more intermediate steps involving one or more α-, β-substituted propionic acid derivatives (II) to obtain MFA (III).

标题 :Preparation of p-fuchsones and synthesis of p-dihydroxylated aromatic compounds therefrom
发明人：COSTANTINI MICHEL; MANAUT DANIEL; MICHELET DANIEL
权利人:RHONE POULENC CHIMIE
摘要:p-Dihydroxylated aromatic compounds are prepared via the oxidation of p-fuchsones, the latter advantageously being synthesized by reacting a phenolic compound having at least one hydrogen atom in the para-position to the hydroxyl function with a non-enolizable ketonic compound, in the presence of a catalytically effective amount of an acid catalyst and, optionally, a cocatalytically effective amount of an ionizable sulfur-containing compound.

标 题 :Dna shuffling of dioxygenase genes for production of industrial chemicals
发明人：SELIFONOV SERGEY A; NEWMAN LISA M
权利人:MAXYGEN INC; SELIFONOV SERGEY A; NEWMAN LISA M
摘要:This invention provides improved polypeptides, including dioxygenases, dehydrogenases, ligases and transferases that are useful for the biocatalytic synthesis of compounds such as α-hydroxycarboxylic acids, and aryl- and alkyl-hydroxy and carboxylic acid compounds. The polypeptides provided herein are improved in properties such as regioselectivity, enzymatic activity, stereospecificity, and the like. Methods for obtaining recombinant polynucleotides that encode these improved polypeptides are also provided, as are organisms that express the polypeptides and are thus useful for carrying out said biocatalytic syntheses. Also provided by the invention are methods for increasing said solvent resistance of organisms that are used in the synthetic methods.

标 题:Combinatorial organic synthesis of unique biologically active compounds
发明人：MCALPINE SHELLI R; TAYLOR RACHEL E; BOLLA MEGAN L; SEGALL ANCA M
摘要:The invention provides a method for making a combinatorial library of cyclic compounds, such as Holliday junction-trapping compounds, comprising the steps of (a) obtaining a plurality of trimers according to the generic structure X 1- X 2- X 3 , wherein X 1 , X 2 and X 3 can be independently any naturally or nonnaturally occurring amino acids or peptidomimetics thereof; (b) optionally coupling a spacer S to the trimer at either end; (c) cyclizing two trimers or trimer-spacer conjugates in a head-to-tail orientation; thereby obtaining a combinatorial library of compounds, wherein the library does not include an unmodifed or naturally occurring Holliday Junction-trapping compounds. The invention additionally provides methods macrocyclic compounds that are synergimycin derivatives.
