专利号:US-2006293466-A1 优先权日:2003-06-20 标 题:Methods for synthesis of graft polymers 发明人:GAUTHIER MARIO; YUAN ZHONGSHUN 权利人:UNIV WATERLOO 摘要:A process for the synthesis of arborescent polymers comprises epoxidation of a first polymer and grafting thereto a second polymer having groups reactive to the epoxide groups on the first polymer. The epoxidation and grafting steps can be repeated. In an additional embodiment, the present invention provides a one-pot method for the synthesis of arborescent polymers. In a reaction pot, a first polymer is copolymerized and then reacted with an activating compound in order to generate a polyfunctional macroinitiator. Monomers are then added to the reaction pot, the monomers having functional groups reactive towards reactive sites on the first polymer.

The present inventions are very useful for the production of well-designed, gold-based architectures. The size- and shape-specific gold nanostructure materials prepared by the present invention may find use as: highly conductive interconnections for single-electron transistors, catalysts for the oxidation of carbon monoxide; biological and chemical sensors; and as contrasting agents for electron microscopic and medical imaging applications.
专利号:EP-0496830-B1 优先权日:1989-10-16 标 题 :Total synthesis of northebaine, normorphine, noroxymorphone enantiomers and derivatives via n-nor intermediates 发明人:RICE KENNER CRALLE; NEWMAN AMY HAUCK 权利人:US HEALTH 摘要:Families of antagonist-agonists and opiate narcotics are produced from norhydrocodeinone. In a preferred embodiment, norhydrocodeinone is refluxed with sulfosalicyclic dimethylketal and delta-6-enol ether derivatives and is then converted entirely to the ether by the addition of dry tetrahydrofuran simultaneously with the removal of the thus produced ether. The ether is then reacted with methanesulfonic acid and N-bromoacetamide to form the hydrobromide salt of the 7-bromodimethylketal derivative. From this derivative, a variety of products can be derived, including the novel further intermediate 14 hydroxynorcodeinone. The present invention enables derivation using a starting material which, unlike the starting materials of prior art processes, is available in the natural (-) or synthetic (+) form. Thus, the method of the present invention provides the only known route for the synthesis of (+) forms of various derivatives and intermediates, such as (+)-7-bromo-dimethylketal nordihydrocodeinone.
