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.

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.

发明人：MESKYS ROLANDAS; JAKUBOVSKA JEVGENIJA; TAURAITE DAIVA
权利人:UNIV VILNIUS
摘要:Disclosed are W-position modified cytidine nucleotides of formula (I). Provided herein are methods of chemical synthesis of AP-modified cytidine nucleoside triphosphates and their applications as well as uses of the cytidine analogues for the synthesis of modified nucleic acids. The nucleic acid molecule includes DNA, RNA or a combination of DNA/RNA. One of many applications of modified cytidine nucleotides described herein is enzyme selection, when an enzyme of interest bears an activity of an esterase, amidase, oxidoreductase, lyase, ligase or other enzymatic activity, formula (I) wherein the substituants are as defined in the appended claims.

标题 :Method for synthesizing lactam derivatives without use of catalyst
发明人：YANG SONG; LI HU; WU HONGGUO
权利人:UNIV GUIZHOU
摘要:Disclosed is a simple synthesis method of lactam derivatives, comprising: with formamide functioning as both an amine source and a hydrogen source (hydrolyzed to produce formic acid), carrying out a cycloamination reaction on a raw material keto acid in the absence of a solvent or a catalyst to simply synthesize a lactam derivative. Compared with previous reports, the present disclosure has the following advantages: the time required for the reaction is greatly shortened, the selectivity is remarkably improved, a conversion rate of a keto acid derivative is greater than 99%, and the yield of the lactam derivative can reach 70% to 94%.
