专利号:US-8088740-B2 优先权日:2009-05-04 标题:Gold binding peptides and shape-and size-tunable synthesis of gold nanostructures 发明人:HUR HOR GIL; KIM JUNG OK; KIM DAE HEE; MYUNG NO SANG 权利人:HUR HOR GIL; KIM JUNG OK; KIM DAE HEE; MYUNG NO SANG; KWANGJU INST SCI & TECH 摘要:The present invention relates to gold binding peptides and shape- and size-tunable synthesis of gold nanostructures. 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:US-6737504-B2 优先权日:2001-07-30 标 题 :Synthesis of substituted poly(aniline)s 发明人:FREUND MICHAEL S; SHOJI EIICHI 权利人:CALIFORNIA INST OF TECHN 摘要:A method for preparing a wide range of substituted poly(aniline)s from a single precursor is described. The method uses a variety of reactions, including a boron activation/electrophilic displacement reaction resulting in ipso-substitution. The ability to tune the properties of poly(aniline) through the generation of new structures is useful in numerous fields ranging from polymer-based electronics to sensors.
专利号:US-4080334-A 优先权日:1968-11-22 标题:Intermediates in the total synthesis employing substituted isoxazole derivatives 发明人:SAUCY GABRIEL; SCOTT JOHN WILLIAM 权利人:HOFFMANN LA ROCHE 摘要:The intermediates and processes of this invention provide a new synthetic route for the preparation of pharmaceutically valuable 19-norsteroids. Further, the intermediates and processes of the invention provide a route for the preparation of pharmaceutically valuable estrones. The present invention provides a facile total synthesis of 19β-alkyl-C/D-trans-steroidal materials. This desirable result is obtained via a unique asymmetric induction followed by subsequent stereo-specific reaction steps. As a precursor to the steroidal Ring A, a 3,5-disubstituted-4-isoxazolylmethylene group is employed in this synthesis.

Importantly, the reaction is stereospecific and is especially valuable for synthesis of symmetrical functionally substituted dienes, biaryls and polyenes.
