标 题:Methods for the solid phase synthesis of combinatorial libraries of benzimidazoles benzoxazoles benzothiazoles and derivatives thereof
发明人:LABORDE EDGARDO; MATSUMOTO YUKIHARU
权利人:TELIK INC
摘要:The present invention provides an efficient and versatile method for the synthesis and screening of combinatorial libraries of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof. In order to expedite the synthesis of large arrays of compounds possessing these core structures, a general methodology for solid phase synthesis of these derivatives is provided. Arrays of benzimidazoles, benzoxazoles, benzothiazoles, and derivatives thereof useful as peptidomimetics and for the identification of agents having antifungal, antiviral, antimicrobial, anticoagulant, and antiulcer activity, or use in the treatment of inflammation, hypertension, cancer, and other conditions can be prepared by this method.

标题:Synthesis of macrocyclic tetraamido-N ligands

权利人:UNIV CARNEGIE MELLON
摘要:New synthetic methods for the preparation of macrocyclic amido-N donor ligands are provided. The primary method of the present invention involves in general only two synthetic steps. In the first step, an α or β amino carboxylic acid is allowed to react with an optimal (approximately stoichiometric) amount of an activated malonate or oxalate derivative with mild heating. Upon completion of the double coupling reaction, hydrolysis of the reaction mixture yields a diamide containing intermediate (a macro linker). In the second step, stoichiometric amounts of a diamine, preferably an orthophenylene diamine, are added to the macro linker intermediate in the presence of a coupling agent and heat. This second double coupling reaction, is allowed to proceed for a period of time sufficient to produce a macrocyclic tetraamido compound. The substituent groups on the α or β amino carboxylic acid, the malonate, and the aryl diamine may all be selectively varied so that the resulting tetraamido macrocycle can be tailored to specific desired end uses. The macrocyclic tetraamide ligand may then be complexed with a metal, such as a transition metal, and preferably the middle and later transition metals, to form a robust chelate complex suitable for catalyzing oxidation reactions.

标 题 :Solvent systems for synthesis of poly(amic acid) and polyimide polymers

权利人:DOW GLOBAL TECHNOLOGIES LLC
摘要:The process for synthesizing a poly(amic acid) polymer or a polyimide polymer is improved by using a solvent system consisting essentially of: (A) a first component consisting essentially of at least one of a sulfoxide, e.g., DMSO, and an alkyl phosphate, e.g., triethyl phosphate, and (B) optionally, a second component consisting essentially of at least one aprotic glycol ether, e.g., dipropylene glycol dimethyl ether.
