摘要:几种吡啶和嘧啶羧酸被合成为视黄酸核受体,视黄酸受体(rars)和视黄酸x受体(rxrs)的配体候选物.虽然吡啶衍生物,6-[(5,6,7,8-四氢-5,5,8,8-四甲基-2-萘基)氨基甲酰]吡啶-3-羧酸(2B)和6-[(5,6,7,8-四氢-5,5,8,8-四甲基-2-萘基)羧酰胺]吡啶-3-羧酸(5B)比相应的苯甲酸型视黄酸更有效,如am80(2A)和am580(5A),但将am580(5A),Am555(6A)或am55(7A)的苯环替换为嘧啶环会导致视黄酸活性在hl-60细胞分化试验和使用cos-1细胞的rar转录激活试验中丧失.另一方面,具有二苯胺骨架(da系列,8和9)的强效rxr激动剂(视黄酸协同剂)的嘧啶类似物(pa系列,10和11)在hl-60细胞分化试验中表现出强效的视黄酸协同活性并激活rxrs.在合成的化合物中,2-[n-正丙基-N-(5,6,7,8-四氢-5,5,8,8-四甲基-2-萘基)氨基]嘧啶-5-羧酸(pa013,10E)在hl-60试验中是最活跃的视黄酸协同剂.

标 题 :Synthesis of ammonium dinitramide (ADN)
发明人：EK STEFAN; JOHANSSON JONAS
权利人:TOTALFOERSVARETS FORSKNINGSINSTITUT
摘要:The invention concerns a method for making ammonium dinitramide from guanylurea dinitramide in one single process step. Guanylurea dinitramide is reacted with an ammonium sulfate in a reaction solution comprising water and acetone and an ion exchange gives ammonium dinitramide. By using acetone the yield is increased compared to known processes as formed guanylurea sulfate is poorly soluable in a water-acetone solution and precipitates, while guanylurea dinitramide has higher solubility in the solution than in only water. The guanylurea sulfate precipitate formed in the reaction solution that contains acetone is less sticky than if formed in water or in a water-alcohol solution and therefore easier to filter off. The use of acetone also allows lower process temperatures to be used than in previously known methods for producing guanylurea dinitramide. Conclusively, the method gives a higher yield, demands considerable smaller amounts of solvent and allows lower process temperatures to be used than in any formerly known process.

摘要:There is described the stereoselective total synthesis of novel DELTA 2,3-1,4-morpholine-2-carboxylic acids possessing a fused beta -lactam ring in the 1,6-position and carrying a substituent cis to carbon 5 in the 7-position of the fused ring system represented by the general formula I wherein Z is halo or hydroxyl and X is acylamino. Also included in the invention are compounds of the above formula in which the carboxyl group at the 2-position is protected as by an easily cleavable ester group and salts of both the free acids and carboxyl-protected compounds. The compounds are potent antibacterial agents.

摘要:The invention concerns a method for making ADN from GUDN in one single process step. GUDN is reacted with an ammonium source (ammonium-sulfamate, ammonium-sulfate, ammonia) and an ion-change gives ADN from GUDN in one process stage. The advantages are that the process gives pure ADN without potassium contaminants and that a smaller amount of solvent is necessary.

摘要:There is provided macrostructures of porous inorganic material which can have controlled size, shape, and/or porosity and a process for preparing the macrostructures. The macrostructures comprise a three-dimension network of particles of porous inorganic materials. The process for preparing the macrostructures involves forming an admixture containing a porous organic ion exchanger and a synthesis mixture capable of forming the porous inorganic material and then converting the synthesis mixture to the porous inorganic material. After formation of the composite material, the porous organic ion exchanger can be removed from the composite material to obtain the macrostructures.

摘要:There is provided a catalyst containing porous macrostructures comprised of: (a) a three-dimensional network of particles of porous inorganic material (e.g., zeolites); and, (b) at least one metal (e.g., a catalytically active metal). The particles of the at least one macrostructure occupy less than 75% of the total volume of the at least one macrostructure and are jointed together to form a three-dimensional interconnected network. The three-dimensional interconnected network will usually be comprised of pores having diameters greater than about 20 Ã…. The macrostructures can be made by forming an admixture containing a porous organic ion exchanger (e.g., a polymer-based ion exchange resin) and a synthesis mixture (e.g., for zeolite formation) capable of forming the porous inorganic material and the at least one metal; converting the synthesis mixture to the porous inorganic material; and removing the porous organic ion exchanger from the inorganic material. The metal-containing macrostructures find application in hydrocarbon conversion (e.g., hydrogenation, dehydrogenation, dehydrocyclization, isomerization, hydrocracking, dewaxing, reforming, conversion of alkyl aromatics, etc.) and in the reduction of emissions of hydrocarbons, carbon monoxide, and/or oxides of nitrogen from an internal combustion engine.
