标题:Synthesis of steroids
发明人：BUNES LEONARD A; JOHNSON WILLIAM S
权利人:STANFORD LELAND JUNIOR UNIV TR
摘要:Method and compounds are provided for use in the synthesis of steroids wherein a polyolefin is provided having an initiating group having a chalcogen atom in juxtaposition to a double bond, so as to be capable of bond formation to close to form a ring and having a terminating group involving pi unsaturation (a double or triple bond) conjugated to an aromatic ring. Upon acid catalysis, sigma bonds are formed through the interaction of a carbocation formed at the carbon atom bonded to the chalcogen atom and the double bond intermediate the initiating group and the terminating group, which close to form rings of a steroid nucleus, the carbocation interacting with the pi unsaturation conjugated with the aromatic group and being captured by a nucleophile present in the acidic reaction medium. The resulting steroid product may then be modified in known ways to produce known steroids.

标题 :Ion-exchange structures of copolymer blends
发明人：MOLNAR CHARLES J; PRICE EDWARD H; RESNICK PAUL R
权利人:DU PONT
摘要:Ion-exchange films, membranes and laminar structures incorporating a layer of a blend of a first fluorinated polymer which contains sulfonyl groups in ionizable form and a second fluorinated polymer which contains carboxylic acid functional groups, when used to separate the anode and cathode compartments of an electrolysis cell, permit operation at high current efficiency and low power consumption. They can be made by synthesis of precursor polymers in melt-fabricable form, blending, fabrication of the film, membrane or laminar structure, and hydrolysis of the functional groups to ionizable form, such as the free acid form or alkali metal salt thereof.

标题:Synthesis of highly fluorinated aromatic compounds
发明人：MARSELLA JOHN A; PEZ GUIDO P; COUGHLIN ANNE M
权利人:AIR PROD & CHEM
摘要:A process is disclosed for making a highly fluorinated aromatic compound by contacting a perfluorocycloalkane, such as perfluorodecahydronaphthalene, with a complex of a metal from Groups IA and IIA of the Periodic Table and an organic electron acceptor. The reaction is carried out in an organic solvent and under reducing conditions which are relatively moderate. Best results are obtained using a perfluorocycloalkane having 2-4 condensed rings and a complex of either sodium or lithium and benzophenone thereby making a perfluorinated condensed ring aromatic compound such as perfluoronaphthalene or perfluorophenanthrene.

标题 :Optically active quaternary ammonium salt, process for producing the same, and process for producing optically active α-amino acid derivative with the same
发明人：MARUOKA KEIJI
权利人:TOSOH CORP
摘要:There are provided (1) an optically active α-amino acid derivative, a stereoselectively useful intermediate for the synthesis of pharmaceutical or agrochemical products, which derivative is an optically active quaternary ammonium salt that, when used as an axially chiral spiro phase-transfer catalyst in the asymmetric alkylation of a glycine derivative, gives a high stereoselectivity toward substrates having a small molecule such as methyl iodide, or secondary alkyl halides, and a method for producing the same; and (2) a novel optically active quaternary ammonium salt that is a high performance axially chiral spiro phase-transfer catalyst used in the asymmetric alkylation of a glycine derivative, and in which each ring of the spiro-structure has the same structure that is advantageous in terms of the number of steps involved in the synthesis of the catalyst, and a method for producing the same and a method for recovering the same. n (Solving means): To achieve the objects, (1) an axially chiral spiro-ammonium salt that incorporates an alkyl- or aryl-substituted silyl group as a substituent on the aromatic ring is used as a phase-transfer catalyst in the asymmetric alkylation of a glycine derivative, and (2) an axially chiral spiro-ammonium slat that incorporates a substituent encompassing a perfluoro alkyl group is used in the asymmetric alkylation of a glycine derivative and thereafter is recovered using a fluorous solvent.
