标题:Materials and methods for the photodirected synthesis of oligonucleotide arrays
发明人：SERAFINOWSKI PAWEL JERZY; GARLAND PETER BRYAN
权利人:CANCER RES INST ROYAL
摘要:Materials and methods for photodirected synthesis of oligonucleotide arrays on a solid substrate by photodirected synthesis are disclosed which employ a film formed from (i) a photoacid generator that on photolysis generates acid that is capable of directly removing the protecting group of the linker molecules or oligonucleotides and (ii) a polymer substantially lacking electronegative heteroatoms that are capable of hydrogen bonding with photogenerated acid. Methods of synthesizing an oligomer arrays are also described that use a film that restricts diffusion of reactants and products on the substrate during synthesis of the array and which includes a precursor of a deprotecting reagent. The method involves removing one or more of the non-required products of the deprotection reaction from the reactive array elements at which they are produced during the reaction, in order to displace the deprotection reaction towards completion.

标题:Transition metal complexes in the controlled synthesis of polyolefins substituted with functional groups
发明人：TAGGE CHRISTOPHER D; WILSON ROBERT B
摘要:A method is provided for the polymerization of olefins substituted with a functional group using a transition metal catalyst that, by virtue of one or more stabilizing groups incorporated within the catalyst structure, “fixesâ€? the stereoconfiguration of each olefinic monomer relative to the transition metal complex during each successive reaction in the polymerization process. The invention substantially reduces the likelihood of olefin rearrangement at the active site of the catalyst during polymerization. In one particular embodiment, the functional group is a polar, electron-donating group and the stabilizing group is a Lewis acid substituent; examples of polymers that can be prepared with such a system include poly(vinyl acetate), poly(vinyl alcohol), and poly(vinyl ethers). Novel complexes and catalyst systems useful in the polymerization method are also provided.

摘要:An unsaturated (meth) acrylic compound of formula: (I) (X=O, S, NH, NR3 (R3=C1-12-alkyl) or O-(CH2)n (where n=1-16 approximately); R2=C2-20 straight-chain or branched alkyl, monocyclic or polycyclic cycloalkyl or heterocycloalkyl, or alkylaryl hydrocarbon chain, comprising an olefinic double bond in the chain, or at the end of the chain in the case of alkyl or alkylaryl, or an exocyclic or endocyclic olefinic double bond in the case of monocyclic or polycyclic cycloalkyl or heterocycloalkyl; and R1=H or C1-5-alkyl), is reacted at 10 DEG -60 DEG C. with at least one oxidising compound (hydrogen peroxide) in the presence of at least one catalyst (alkali metal molybdates and tungstates) and in the presence of at least one phase transfer agent and when R2=polycyclic cycloalkyl or hetercycloalkyl, an organic peracid or hydrogen peroxide in the presence of at least one heteropolyacid. To open the epoxide function, the epoxide obtained is reacted with a compound chosen from strong inorganic acids, boron trifluoride etherate complexes, acid salts in the presence of the corresponding acid, halides of trialkylsilanes or trialkoxysilanes, and ketones in the presence of cationic resins.

摘要:The present invention relates to a process for stereoselective or regioselective chemical synthesis which generally comprises reacting a nucleophile and a chiral or prochiral cyclic substrate in the presence of a non-racemic, chiral catalyst to produce a stereoisomerically- and/or regioisomerically-enriched product. The present invention also relates to hydrolytic kinetic resolutions of racemic and diastereomeric mixtures of epoxides.

标题:Polymerization initiator for living radical polymerization

摘要:Provided is a method of living radical polymerization which does not necessitate complicated and intricate synthesis of a dormant species and which is highly efficient. A halogenated derivative compound is used as a dormant species for initiating living radical polymerization. The derivative compound is obtained by halogenating an alcohol compound having a non-conjugated structure or an amine compound having a non-conjugated structure with a halogenating agent capable of halogenating an alcohol or amine. A radical produced by elimination of halogen from the halogenated derivative compound is allowed to react with the unsaturated bond of the monomer. Thus, the monomer, which has a radical-reactive unsaturated bond, is polymerized by living radical polymerization. Preferably, the halogenating agent is a compound (NIS or the like) which also has a function as a catalyst.
