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.

专利号:US-7749300-B2 优先权日:2008-06-05 标题 :Photochemical synthesis of bimetallic core-shell nanoparticles 发明人:CHRETIEN MICHELLE N; WU YILIANG; CHOPRA NAVEEN 权利人:XEROX CORP 摘要:A method of forming bimetallic core-shell metal nanoparticles including a core of a first metal material and a shell of a second metal material, the method including photochemically producing metallic nanoparticle cores of the first metal material, and forming a shell of the second metal material around the cores. The shell can be formed by adding shell-forming precursor materials to a solution or suspension of the cores and photochemically forming the shells around the cores, or by separately photochemically producing metallic nanoparticles of the second metal material and mixing the metallic nanoparticles of the second metal material and the metallic nanoparticle cores to cause the metallic nanoparticles of the second metal material to form a shell around the metallic nanoparticle cores.
专利号:US-2005080260-A1 优先权日:2003-04-22 标 题 :Preparation of prodrugs for selective drug delivery 发明人:MILLS RANDELL L; WU GUO-ZHANG 摘要:Synthesis of a chemical compound having the formula A-B-C that may serve for applications such as drug delivery where A is a chemiluminescent, moiety, B is a photochromic moiety, and C is a biologically active moiety where A-B-C may serve as a prodrug. Novel synthetic methods of the present invention to form the prodrug comprised the steps of (1) forming a benzophenone, (2) forming a diaryl ethylene, (3) attaching a phthalimide moiety to at least one of the aryl groups of the ethylene to form a phthalimide-ethylene conjugate, (4) condensing two ethylene-phthalimide conjugates to form a phthalimide-pentadiene conjugate, (5) converting the phthalimide to the phthalhydrazide by reaction with hydrazine to form a carrier compound according to the present invention, and (6) reacting the carrier compound with an nucleophilic moiety of the drug to form the corresponding prodrug. Alternatively the carrier can be prepared by using the halo-substituted diaryl ethylene to make the corresponding cationic leuco dye-like compound with known methods. The cationic compound then is protected by reacting with a nucleophile and coupled with the aminophathalimide by palladium-catalyzed amination to form the protected phthalimide-pentadiene conjugate. The latter is refluxed with hydrazine to convert its phthalimide to the phthalhydrazide and acidified to give the carrier. An additional aspect of the present invention relates to the use of these compounds as antiviral agents for the treatment of viral infections such as HIV and as anticancer agents for the treatment of cancers such as bowel, lung, and breast cancer.
专利号:US-9573119-B2 优先权日:2011-09-16 标题 :Process for preparing V—Ti—P catalysts for synthesis of 2,3-unsaturated carboxylic acids 发明人:DENG LIU; NORMAN DAVID WILLIAM; TUSTIN GERALD CHARLES; BOPPANA BHARAT VENKATA; STEFFEY MELISSA PAGE 权利人:EASTMAN CHEM CO 摘要:The invention relates to a catalyst composition comprising a mixed oxide of vanadium, titanium, and phosphorus. The titanium component is derived from a water-soluble, redox-active organo-titanium compound. The catalyst composition is highly effective at facilitating the vapor-phase condensation of formaldehyde with acetic acid to generate acrylic acid, particularly using an industrially relevant aqueous liquid feed. Additionally, the catalyst composition is catalytically active towards the formation of acrylic acid from methylene diacetate and methacrylic acid from methylene dipropionate; both reactions are carried out with high space time yields.
