专利号:US-2024400517-A1 优先权日:2022-02-08 标 题 :Chiral bimetallic cooperative catalysis system and use thereof in asymmetric synthesis of bedaquiline 发明人:ZHANG WANBIN; GAO FENG; LI JING; AHMAD TANVEER; ZHANG ZHENFENG; YUAN QIANJIA 权利人:UNIV SHANGHAI JIAOTONG 摘要:A chiral bimetallic cooperative catalysis system and use thereof in asymmetric synthesis of bedaquiline are provided. Specifically, the chiral bimetallic cooperative catalysis system is formed by a metallic lithium, sodium or potassium salt and another metal salt under the action of a suitable ligand and an additive. By means of the chiral bimetallic cooperative catalysis system, an addition reaction of 6-bromo-3-benzyl-2-methoxyquinoline (I) and 3-dimethylamino-1-naphthyl-1-propanone (II) is promoted, the selectivity is regulated, and a target product, (1R,2S)-bedaquiline, with high yield and high selectivity is obtained for the first time.

专利号:US-10925977-B2 优先权日:2006-10-05 标 题 :Efficient synthesis of chelators for nuclear imaging and radiotherapy: compositions and applications 发明人:YANG DAVID J; YU DONGFANG; THOMPSON ANDREW S 权利人:YANG DAVID J; YU DONGFANG; THOMPSON ANDREW S; CEIL POINT LLC; UNIV TEXAS 摘要:Novel methods of synthesis of chelator-targeting ligand conjugates, compositions comprising such conjugates, and therapeutic and diagnostic applications of such conjugates are disclosed. The compositions include chelator-targeting ligand conjugates optionally chelated to one or more metal ions. Methods of synthesizing these compositions in high purity are also presented. Also disclosed are methods of imaging, treating and diagnosing disease in a subject using these novel compositions, such as methods of imaging a tumor within a subject and methods of diagnosing myocardial ischemia.
专利号:US-2008146772-A1 优先权日:2006-11-02 标题 :Materials and methods for co-crystal controlled solid-state synthesis of imides and imines 发明人:ZAWOROTKO MICHAEL J; CHENEY MIRANDA L 权利人:UNIV SOUTH FLORIDA 摘要:The subject invention pertains to methods for solid-state synthesis of imides and imines using co-crystals. The co-crystal formers utilized are substrates of condensation reactions and co-crystals can be obtained in high yield via methods such as slurrying, solvent evaporation, solvent crystallization, treatment with supercritical fluid(s), melting plus crystallization, slurry conversion, grinding of solids, blending of powders, heating of solids, solvent-drop grinding, or grinding plus melting.
专利号:US-2025214849-A1 优先权日:2023-12-28 标 题:Synthesis of porous crystalline materials in the presence of water-soluble oxidized disulfide oil and fluoride mineralizer 发明人:HODGKINS ROBERT PETER; KOSEOGLU OMER REFA 权利人:SAUDI ARABIAN OIL CO 摘要:Methods are provided for hydrothermal synthesis of porous crystalline materials. The method generally comprises forming a solution of precursors and reagents in effective ratios for a porous crystalline material including a fluoride-containing mineralizer, and water-soluble oxidized disulfide oil. The solution is hydrothermally treated under effective conditions and for an effective time to synthesize porous crystalline materials.
