标题:Synthesis of beta-lactams from azetidine carboxylic acid esters
发明人：LIPSHUTZ BRUCE H; WASSERMAN HARRY H; WU JAMES S
权利人:RESEARCH CORP
摘要:Azetidine carboxylic acid esters are converted into enol silyl ethers which, as enamino ketene acetals, undergo ready oxidative cleavage of the ethylenically unsaturated double bond, e.g. by dye-sensitized photo-oxygenation, to form beta-lactams. The beta-lactams and substitution products thereof are useful intermediates in the synthesis of biologically active lactams.

标题:Oxidoreductase inhibitors and methods of screening and using thereof
发明人：BALENDIRAN GANESARATNAM K
摘要:The present invention relates to 1) the design and synthesis of analogs to glutathione conjugates which bind to or interact with aldose reductase (AR) through unique conformations that are distinctly different from the substrates and inhibitors of AR which are members of sugar metabolism; 2) the screening of the analogs to identify those that interact with or inhibit or enhance the activity of AR; and 3) the use of AR ligands, AR inhibitors (AR antagonsits) or AR enhancer (AR agonists) in the detection of AR activity, the modulation of AR activity, and the treatment of conditions in a subject in need of modulating AR activity. Such conditions include but not limited to cardiovascular disease, diabetes, artheriosclerosis, cancer, neoplasm, obesity, cataract, retinopathy, keratopathy, nephropathy, neurosis, thrombosis, faulty union of corneal injury and neuropathy. Examples of the treatment include the use of fibrates as AR inhibitors to treat these conditions.

权利人:SHINETSU CHEMICAL CO
摘要:A process for the preparation of phosphonium salts by the use of chlorides, which is useful in the course of synthesis of olefin compounds by the Wittig reaction, and which comprises reacting a phosphine compound of the general formula R13P wherein R1 is a phenyl group or a straight-chain alkyl group having 2 to 8 carbon atoms, with a primary or secondary chloride of the general formula wherein R2 and R3 are hydrocarbon radicals, in a solvent selected from the group consisting of N,N-dimethylformamide, N,N-dimethylacetamide and N,N-1,3-dimethyl-2-imidazolidinone, and in the presence of an alkali metal salt of the general formula MBr or MI.
