标题:Universal linker reagents for dna synthesis
发明人：REED MICHAEL W; WU CHENG-HSIEN; COOPER JOHN; DEMPCY ROBERT O
权利人:GENSCRIPT USA INC; CUSTOMARRAY INC
摘要:Provided herein are methods and compositions for oligonucleotide synthesis utilizing universal linker phosphoramidites. Methods and reagents are described with DNA synthesis using controlled pore glass (CPG) solid supports, and on platinum coated electrodes for electrochemical DNA synthesis. The universal linkers can be used as spacers in single-column PCR primer synthesis to generate 2 strands with free 3′-hydroxy termini after cleavage. The methods and compositions utilize a solid support system for synthesis of oligonucleotides, wherein the support has platinum electrodes and a universal linker, optionally wherein the platinum electrode is coated with an amine. The methods and compositions further describe use of universal linker phosphoramidites and the platinum electrode is coated with a monosaccharide, or a disaccharide.

摘要:A process for synthesizing 5-((2-methyl-1H-imidazol-1-yl)methyl)furan-2-carbaldehyde from a mixture comprising a carbohydrate, an alkali or alkaline-earth metal chloride, hydrochloric acid, water, an organic solvent, namely a water-insoluble polar aprotic solvent, and optionally a phase-transfer agent, proceeds via the formation of 5-(chloromethyl)furan-2-carbaldehyde, without isolating this synthesis intermediate. A process also synthesizes a compound of formula (III) below:from 5-((2-methyl-1H-imidazol-1-yl)methyl)furan-2-carbaldehyde.

标题 :Synthesis of furans from sugars via keto intermediates
发明人：BINDER JOSEPH B
权利人:BP CORP NORTH AMERICA INC
摘要:The present invention provides a method of preparing a furan derivative comprising the steps of (a) converting a monosaccharide to provide a keto-intermediate product; and (b) dehydrating the keto-intermediate product to provide a furan derivative; wherein the keto-intermediate product is pre-disposed to forming keto-furanose tautomers in solution. The method may further comprise a step of oxidizing the furan derivative to provide a furandicarboxylic acid or a furandicarboxylic acid derivative.

标题:Catalytic synthesis of delta-valerolactone (dvl) from furfural-derived 2-hydroxytetrahydropyran (hthp)

权利人:WISCONSIN ALUMNI RES FOUND
摘要:A method to make delta-valerolactone (“DVLâ€?) by dehydrogenating 2-hydroxytetrahydropyran (“HTHPâ€?). The HTHP is contacted with a supported-metal catalyst for a time, at a temperature, and at a pressure wherein at least a portion of the HTHP is converted to DVL via dehydrogenation of the HTHP. The HTHP may be derived from biomass. Thus, the method yields DVL without requiring a petroleum-based feedstock.
