专利号:US-8084007-B2 优先权日:2004-01-30 标题 :Methods of synthesis of isotropically enriched borohydride and methods of synthesis of isotropically enriched boranes 发明人:SPIELVOGEL BERNARD; COOK KEVIN S 权利人:SPIELVOGEL BERNARD; COOK KEVIN S; SEMEQUIP INC 摘要:The invention provides new methods for the synthesis of isotopically enriched metal borohydrides, metal tetrahydroundecaborate salts, and decaborane from isotopically enriched 10 B-boric acid or 11 B-boric acid. The invention is particularly useful for synthesis of isotopically enriched sodium or lithium borohydride, MB 11 H 14 (where M is Li, Na, K, or alkylammonium), and decaborane.
专利号:US-8258299-B2 优先权日:2009-03-27 标题:Process for preparation of temsirolimus 发明人:LEE KWANG-CHUNG; LEE TING-HUEI; TUNG YEN-SHIH; KAO CHIA-CHEN; LEE TZU-AI 权利人:LEE KWANG-CHUNG; LEE TING-HUEI; TUNG YEN-SHIH; KAO CHIA-CHEN; LEE TZU-AI; CHUNGWA CHEMICAL SYNTHESIS & BIOTECH CO LTD 摘要:The present invention provides two synthetic routes for the preparation of Temsirolimus (compound 1b and analog of Temsirolimus 1a). The first route includes the synthesis of CCI-779 by directly reacting rapamycin (4b) or Prolyl-rapamycin (4a) with substituent-2,2-bis(methoxy) propionic acid anhydride(11) in the presence of an organic base, followed by deprotection to give CCI-779 or Proline CCI-779. The second route includes a process involving a reaction of rapamycin-OH-31-sily ether (4d) or Prolyl-rapamycin-OH-31-sily ether (4c) with substituent-2,2-bis(methoxy) propionic acid anhydride(11) in the presence of an organic base and followed by subsequent hydrolysis step to obtain the desired CCI-779 or Proline CCI-779. n Compound 11, as described in this invention, is stable at room temperature, cost effective and ease of processing.

In said formula, R is H or optionally protected OH.
专利号:US-8354524-B2 优先权日:2001-03-22 标 题:Synthesis of selenium-derivatized nucleosides, nucleotides, phosphoramidites, triphosphates and nucleic acids 发明人:HUANG ZHEN 权利人:UNIV GEORGIA STATE RES FOUND; HUANG ZHEN 摘要:The present invention provides selenium derivatives of nucleosides, nucleoside phosphoramidites, nucleotides, nucleotide triphosphates, oligonucleotides, polynucleotides, and larger nucleic acids and methods for their synthesis. Selenium derivatives of both ribonucleic acids and deoxyribonucleic acids, as well as methods for their synthesis, crystallization and uses in structural determinations, particularly by X-ray crystallographic techniques are disclosed. The selenium derivatives of the present invention are also useful as food supplements.
专利号:US-2005003188-A1 优先权日:2003-03-21 标题 :Thermolytic synthesis of inorganic oxides imprinted with functional moieties 发明人:BASS JOHN D; KATZ ALEXANDER 权利人:UNIV CALIFORNIA 摘要:Inorganic oxides, particularly silica or germania or inorganic oxides containing silica and/or germania, are imprinted with one or a plurality of functional moieties such as amine and/or thiol groups by a process featuring incorporating such groups into the oxide by use of a thermally labile material containing a protecting group for the amine or thiol, followed by removal of the thermally labile moiety by thermolysis. The resulting products are inorganic oxide substrates or bulk inorganic oxides imprinted with the functional moieties. A plurality of such moieties may be imprinted on a substrate in an order fashion using a polymeric imprinting compound, and may then be used as a templated array of functional moieties to which ordered metallic nanostructures may be constructed.
