专利号:US-7943594-B2 优先权日:2002-07-10 标 题 :Solid-phase and solution-phase synthesis of glycosylphosphatidylinositol glycans 发明人:SEEBERGER PETER H; HEWITT MICHAEL C; SNYDER DANIEL A 权利人:MASSACHUSETTS INST TECHNOLOGY 摘要:One aspect of the present invention relates to solution-phase approaches to GPI synthesis. Another aspect of the present invention relates to key building blocks, and syntheses thereof, useful for GPI assembly. Yet another aspect of the invention relates to an automated method for the synthesis of GPIs and fragments thereof.
专利号:US-5545568-A 优先权日:1992-09-14 标题:Solid phase and combinatorial synthesis of compounds on a solid support 发明人:ELLMAN JONATHAN A 权利人:UNIV CALIFORNIA 摘要:Methods, compositions, and devices for synthesizing combinatorial libraries of various useful compounds, such as benzodiazepines, prostaglandins, β-turn mimetics and glycerol-derived drugs is described. In order to expediently synthesize such combinatorial libraries of derivatives based upon these core structures, a general methodology for the solid phase synthesis of these derivatives is also provided. This disclosure thus also describes an important extension of solid phase synthesis methods to nonpolymeric organic compounds.
专利号:EP-1721894-A1 优先权日:2005-05-13 标题 :Process for the synthesis of prostaglandin derivatives 发明人:LISI GIUSEPPE 权利人:TECHNOPHARMA SA 摘要:An alternative method for the synthesis of prostaglandin F analogues, in particular, analogues of PGF 2α and specifically for the synthesis of latano-prost, wherein the transformation of the lactone intermediate (5)n ninto the corresponding lactol (7)n nis carried out by treating the lactone intermediate (5) with a silane, preferably polymethylhydrosiloxane (PMHS), in the presence of a titanocene - and preferably titanocene fluoride. n The method enables considerable production economies with respect to the conventional reduction of lactone with diisobutylaluminum hydride (DIBAL-H).
专利号:WO-2017033128-A1 优先权日:2015-08-25 标题 :Biphenyl-substitued 4-amino-butyric acid derivatives and their use in the synthesis of nep inhibitors 发明人:HOOK DAVID; KU JIE; ZHOU JIANGUANG 权利人:NOVARTIS AG; HOOK DAVID; KU JIE; ZHOU JIANGUANG 摘要:The invention relates to a novel process, novel process steps and novel intermediates useful in the synthesis of pharmaceutically active compounds, in particular neutral endopeptidase (NEP) inhibitors and prodrugs thereof.
专利号:US-12240835-B2 优先权日:2018-09-18 标题:Substituted benzamides as intermediates in the synthesis of inhibitors of tyrosine kinase enzymatic activity 发明人:ROMERO F ANTHONY; KIRSCHBERG THORSTEN A; HALCOMB RANDALL; XU YINGZI 权利人:TERNS PHARMACEUTICALS INC 摘要:Provided herein are compounds, preferably compounds inhibiting tyrosine kinase enzymatic activity of a protein selected from Abelson protein (ABL1), Abelson-related protein (ABL2), or a chimeric protein BCR-ABL1, compositions thereof, and methods of their preparation, and methods of inhibiting tyrosine kinase enzymatic activity of a protein selected from Abelson protein (ABL1), Abelson-related protein (ABL2), or a chimeric protein BCR-ABL1, and methods for treating diseases wherein modulation of BCR-ABL1 activity prevents, inhibits, or ameliorates the pathology and/or symptomology of the disease. Intermediates such as compounds of Formula (S23), which are useful in the synthesis of compounds inhibiting tyrosine kinase enzymatic activity of a protein selected from Abelson protein (ABL1), Abelson-related protein (ABL2), or a chimeric protein BCR-ABL1, are also provided.
专利号:US-10173993-B2 优先权日:2015-12-09 标题 :Process for the synthesis of sulfones and sulfonamides 发明人:VON WOLFF NIKLAS; CHAR JOËLLE; CANTAT THIBAULT 权利人:COMMISSARIAT ENERGIE ATOMIQUE 摘要:A one pot single step process is described for the synthesis of a compound, including a labeled compound, containing a sulfonyl functional group comprising the step of mixing together a silane, an SO 2 source, an electrophilic compound, an activating compound and optionally a metal catalyst. A process for producing tracers from a labeled sulfonyl containing compound prepared by the described process is also included.
