标题:Synthesis of indoles from anilines and intermediates therein
发明人：GASSMAN PAUL G
权利人:UNIV OHIO STATE RES FOUND
摘要:Preparing indoles and intermediates therefor by reacting an N-haloaniline with a β-carbonylic hydrocarbon sulfide to form an azasulfonium halide, reacting the azasulfonium halide with a strong base to form a thio-ether indole derivative, and then reducing the thio-ether indole, e.g. with Raney nickel, to form the indole compound. When an acetal or ketal of the β-carbonyl hydrocarbon sulfide is used, the azasulfonium salt is treated with a base, and then with an acid to form the thio-ether indole derivative. When an α-ethyl-β -carbonylic hydrocarbon sulfide is used, the resulting azosulfonium salt reacts with strong base to form a thio-ether indolenine derivative, which on reduction with Raney nickel or complex metal hydrides yields 3-substituted indoles. The aniline may be an aminopyridine to form an aza-indole compound in the process. The azasulfonium salts and thio-ether indole or thio-ether indolenine derivatives can be isolated and recovered from their respective reaction mixtures. The thio-ether-indole and thio-ether indolenine derivatives are useful as intermediates to make the indoles without the thio-ether group. The indoles are known compounds having a wide variety of uses, e.g., in making perfumes, dyes, amino acids, pharmaceuticals, agricultural chemicals and the like.

标题:Bicyclic carboxylates as modulators of transporters and uses thereof
发明人：SANDANAYAKA VINCENT; GORECZNY GREGORY
权利人:NIROGY THERAPEUTICS INC
摘要:The present invention generally relates to the field of transporter modulators, e.g., monocarboxylate transporter inhibitors, and more particularly to new bicyclic enone carboxylate compounds, the synthesis and use of these compounds and their pharmaceutical compositions, e.g., in the treatment, modulation and/or prevention of physiological conditions associated with monocarboxylate transporter activity such as in treating cancer and other neoplastic disorders, tissue and organ transplant rejection.

标题 :Polyfluoroalkylthio alcohols, esters and useful compositions therefrom
发明人：DEAR ROBERT E A; BRACE NEAL O
权利人:CIBA GEIGY CORP
摘要:Polyfluoroalkylthio alcohols and esters thereof are disclosed with utility as intermediates for the synthesis of fluorochemicals with low free surface energies having oil and water repellent properties. The novel alcohols and esters are obtained by a free radical catalyzed addition of polyfluoroalkylthiols to acetylenic alcohols or esters thereof. The alcohols are employed in preparation of fluorine containing polyurethanes which are useful as finishes to provide oil and water repellency to textiles and as additives to plastics to provide mold release and other desirable properties.

发明人：DEAR ROBERT ERNEST ARTHUR; FALK ROBERT ALLAN
权利人:CIBA GEIGY CORP
摘要:Perfluoroalkylthio glycols and esters thereof can be prepared by the free-radical catalyzed addition of a perfluoroalkylthiol to an acetylenic alcohol or ester thereof. The compounds obtained are useful intermediates for the synthesis of fluorochemicals with low free surface energies having oil and water repellent properties. In one embodiment, a perfluoroalkylthio glycol can be reacted with a diisocyanate to obtain a polyurethane containing perfluoroalkylthio groups, which polyurethanes are useful as coatings to provide oil and water repellence to textiles and as additives to plastics to provide mold-release and other desirable properties.
