权利人:EASTMAN KODAK CO
摘要:A new synthetic method is reported in which 2-arylbenz(ox,imid,thi)azoles can be prepared by the palladium catalyzed condensation of aromatic halides with o-amino(phenol, aniline, thiophenol)s followed by dehydrative cyclization. This method is tolerant of a wide variety of functional groups on either aromatic ring and gives good to excellent yields of products.

权利人:WISCONSIN ALUMNI RES FOUND
摘要:A solid phase synthetic method for preparing arylretinamides is provided. The method comprises reacting hexachloroacetone with a solvent-suspended resin-bound triphenylphosphine to provide a suspension comprising an activated chlorinating reagent; reacting retinoic acid with the activated chlorinating reagent to provide retinoyl chloride; adding pyridine and a select arylamine to the resulting mixture; and stirring the resulting mixture for a time and at a temperature sufficient for the select arylamine to react with the retinoyl chloride and provide the arylretinamide. Also provided, are select arylretinamides that can be prepared by the present method, and methods of using such arylretinamides to induce apoptosis in cancer cells.

标 题:Electrochemical synthesis of substituted aromatic amines in basic media
发明人：GREGORY THOMAS D; STUTTS KENNETH J
权利人:DOW CHEMICAL CO
摘要:Substituted amino aromatic compounds such as 3-amino-4-hydroxybenzoic acid are prepared by electrolytically reducing the corresponding nitro aromatic compound in a basic medium at temperatures below 60° C. and current densities greater than 50 milliamps per square centimeter. The aminohydroxybenzoic acids are useful in the preparation of polybenzoxazoles which are used to make fibers and composites having high strength and thermal stability.
