摘要:The invention provides a method for manufacturing or preparing neutral, low molecular weight 99m Tc-labeled and 186 Re-labeled carbohydrate complexes with an improved radiochemical yield from a simple functionalized sugar, such as glucosamine. In particular the synthesis relies on single ligand transfer (SLT) or double ligand transfer (DLT) reactions for converting a ferrocene compound into a rhenium or technetium tricarbonyl complex. The ferrocene compound may be linked to a sugar through various functional groups including, for example, thio, amino and alcohol functionalities to provide a wide range of radiolabeled sugar complexes that include both water soluble and relatively water insoluble compounds.

标 题 :Synthesis of liquid fuels and chemicals from oxygenated hydrocarbons
发明人：CORTRIGHT RANDY D; BLOMMEL PAUL G
权利人:VIRENT INC
摘要:Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to hydrocarbons, ketones and alcohols useful as liquid fuels, such as gasoline, jet fuel or diesel fuel, and industrial chemicals. The process involves the conversion of mono-oxygenated hydrocarbons to aromatics and gasoline range hydrocarbons where the oxygenated hydrocarbons are derived from biomass.

标题 :Process for the production of 2-isocyanato-2,3-dehydrocarboxylic acid esters
发明人：EFFENBERGER FRANZ; KUEHLWEIN JUERGEN; DRAUZ KARLHEINZ

摘要:There are produced 2-isocyanato-2,3-dehydrocarboxylic acid esters of the general formula: (I) in which R1 is a straight chain or branched C1-C4-alkyl group, a phenyl group or a benzyl group, R2 is hydrogen or a methyl group and R3 is hydrogen, a straight chain or branched C1-C16-alkyl group, a C3-C8-cycloalkyl group, a C1-C6-alkylmercapto group or a phenyl group by reacting a 2-azido-carboxylic acid ester of the general formula: (II) in an inert solvent at a temperature between 0 DEG and 150 DEG C. with phosgene or diphosgene in the presence of a perrhenate. The compounds of general formula (I) can be converted into the corresponding Z- or BOC-protected 2,3-dehydro-2-amino-carboxylic acid ester with benzyl alcohol or with tert. butyl alcohol, which esters in turn are valuable building blocks for the synthesis of dehydropeptides.

标题:Synthesis of tetrathioperrhenate salts
发明人：WEI LIWEN; HALBERT THOMAS R; STIEFEL EDWARD I
权利人:EXXON RESEARCH ENGINEERING CO
摘要:According to the present invention, an improved method for preparing tetrathioperrhenate salts is provided. Basically, a water soluble, oxygen-containing rhenium compound such as rhenium oxide or a salt containing an oxyanion of rhenium, such as ReO 4 -- , is contacted with an aqueous ammonium sulfide or polysulfide solution in the presence of a cation which is capable of forming an aqueous insoluble salt with tetrathioperrhenate.
