专利号:US-6051704-A 优先权日:1996-07-22 标题:Synthesis of macrocyclic tetraamido-N ligands 发明人:GORDON-WYLIE SCOTT W; COLLINS TERRENCE J 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.

These compounds are generally photolabile and comprise protecting groups which can be removed by photolysis to unmask a reactive group. The protecting group has the general formula Y, wherein Y is a chemical structure as shown in FIG. 1 . Also provided is a method of forming, from component molecules, a plurality of compounds on a support, each compound occupying a separate predefined region of the support, using the protected compounds described above.

专利号:US-5994535-A 优先权日:1989-03-06 标题 :Water soluble texaphyrin metal complex preparation 发明人:SESSLER JONATHAN L; HEMMI GREGORY W; MODY TARAK D 权利人:UNIV TEXAS 摘要:The present invention is directed to methods for synthesizing water soluble hydroxy-substituted texaphyrins retaining lipophilicity. The synthesis comprises condensing a diformyltripyrrole with an ortho-phenylenediamine to give a nonaromatic texaphyrin having at least one hydroxy substituent, and oxidizing the condensation product to form an aromatic texaphyrin metal complex having at least one hydroxy substituent. These expanded porphyrin-like macrocycles may be used for magnetic resonance imaging and for photodynamic therapy in the treatment of atheroma and tumors.
