专利号:US-7956011-B2 优先权日:2005-05-04 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.

In the present invention, an air-stable compounded nickel (II) complex Ni[P(OEt) 3 ]{[R`NC(CH 3 )C(CH 3 )NR`]C}Br 2 is used as a catalyst, wherein R` is 2,4,6-trimethylphenyl, and the α-benzyl benzofuran compound is synthesized by means of a hydrogen heteroarylation reaction of an aryl ethylene compound and a benzofuran compound in the presence of an organic base. The operability and substrate applicability of the catalyst are obviously better than those of the prior art, and meanwhile, the nickel catalyst has a higher practical application value due to the air stability and easiness of synthesis thereof.

One or more alkadiene monomers are polymerized in the presence of suitable organometallic initiators and subsequently coupled to form star polymers. Prior to coupling, one or more alkenylsubstituted aromatic hydrocarbons are incorporated at the living ends of the polydienyl anions to provide increased linking efficiencies.

专利号:US-9403854-B2 优先权日:2001-03-30 标 题 :Cross-metathesis reaction of functionalized and substituted olefins using group 8 transition metal carbene complexes as metathesis catalysts 发明人:GRUBBS ROBERT H; CHATTERJEE ARNAB K; CHOI TAE-LIM; GOLDBERG STEVEN D; LOVE JENNIFER A; MORGAN JOHN P; SANDERS DANIEL P; SCHOLL MATTHIAS; TOSTE F DEAN; TRNKA TINA M 权利人:CALIFORNIA INST OF TECHN 摘要:The invention pertains to the use of Group 8 transition metal carbene complexes as catalysts for olefin cross-metathesis reactions. In particular, ruthenium and osmium alkylidene complexes substituted with an N-heterocyclic carbene ligand are used to catalyze cross-metathesis reactions to provide a variety of substituted and functionalized olefins, including phosphonate-substituted olefins, directly halogenated olefins, 1,1,2-trisubstituted olefins, and quaternary allylic olefins. The invention further provides a method for creating functional diversity using the aforementioned complexes to catalyze cross-metathesis reactions of a first olefinic reactant, which may or may not be substituted with a functional group, with each of a plurality of different olefinic reactants, which may or may not be substituted with functional groups, to give a plurality of structurally distinct olefinic products. The methodology of the invention is also useful in facilitating the stereoselective synthesis of 1,2-disubstituted olefins in the cis configuration.
