标题:通过有机铵盐介导的环硫代酸酐和环硫化物的精确合成,可以合成具有不同结构的聚硫酯.
摘要:具有不同结构的聚(硫酯)的精确合成仍然是聚合物材料领域中的重大挑战.本文中,我们报告了一种通过简单的有机铵盐诱导的环状硫代酸酐和环硫化物的受控交替共聚来合成定义明确的聚(硫代酯)的新方法.阳离子和阴离子都对共聚有很大影响.带有大体积阳离子的[ppn] Oac([ppn] =双(三苯基膦)亚胺)被证明可以有效地引发这种聚合反应,得到具有完全交替结构,可控制的分子量和狭窄的多分散性的聚(硫酯).由琥珀酸硫代酐和硫化丙烯获得的聚(硫酯)是典型的半结晶材料,具有高达1.78的高折射率.

摘要:The objective of the present invention is to provide a monomer for RNA synthesis which can be efficiently produced and therefore by which the producing cost of RNA can be remarkably decreased, and a method for efficiently producing the monomer in a small number of steps. In addition, the objective of the present invention is also to provide a method by which RNA can be efficiently produced even when a approximately stoichiometry amount of the monomer for RNA synthesis is used. The monomer for RNA synthesis according to the present invention is represented by the following formula (I) or (I′): n nwherein R 1 is a protective group of the hydroxy group and R 2 is an alkyl group or the like.

标题:Selective synthesis of 2-haloalkanethiols and episulfides therefrom
发明人：MUELLER WOLFGANG H; OSWALD ALEXIS A; KOZAK PETER J
权利人:EXXON RESEARCH ENGINEERING CO
摘要:Haloalkanethiols are synthesized through the free radical liquid phase reaction of halogenated olefins with an excess of hydrogen sulfide. High product yields to the desired haloalkanethiol products are secured when a 3 to 20 fold molar excess of hydrogen sulfide to halogenated olefin is used. Desirably, the synthesis is carried out to a conversion level not exceeding 90%. The haloalkanethiol products can be subsequently dehydrohalogenated to the corresponding episulfide products by reacting the haloalkanethiol product with a substantially equal molar amount of anhydrous ammonia.

摘要:The invention relates to a process for the anionic polymerization and copolymerization of vinyl, dienic and heterocyclic monomers. According to the invention, the process consists in carrying out the reaction in the presence of an initiator consisting of a molecular combination of an alkali metal amide and the salt of the same alkali metal with at least one hydroxylic compound and in the absence of solvent. The initiator can be prepared by intimately mixing its constituents or in the presence of a solvent of low polarity which is subsequently evaporated off, or in situ in the monomer. Application to the synthesis of special or widely used polymers and copolymers.

摘要:An oligonucleotide continuous synthesis device according to the present invention comprises: a starting material container for storing a blocked protected nucleoside that is a starting material; a first reagent container for storing a reagent used for chain extension of the blocked protected nucleoside; a second reagent container for storing a reagent for a reaction for oxidizing or sulfurizing the phosphate linkage of the extended nucleotide obtained by the chain extension; and a third reagent container for storing a reagent for a reaction for deprotecting the oxidized or sulfurized extended nucleotide. In this device, the starting material, the first reagent, and the second reagent are supplied continuously, thereby performing oligonucleotide synthesis in a flow system.

摘要:The present invention relates to 2-Pyridinone derivatives, more specifically 5-ethyl-6-methyl-2-pyridinone derivatives, according to general formula I that inhibit human immunodeficiency virus type 1 (HIV-1) replication and are therefore of interest in the treatment of Acquired Immune Deficiency Syndrome (AIDS). The present invention further relates to the synthesis of said compounds and their use, with or without other pharmaceutical agents, in the treatment of AIDS and viral infections by HIV-1.
