专利号:US-5856497-A 优先权日:1995-12-11 标题 :Asymmetric synthesis of α-cycloalkylalkyl substituted methanamines 发明人:ROTH GREGORY; LANDI JOHN 权利人:BOEHRINGER INGELHEIM PHARMA 摘要:This invention relates to process for asymmetrically producing enantiomerically pure α-cycloalkylalkyl substitututed methanamines from α-pinene. One key step of the process of this invention utilizes the oxidation product of α-pinene, hydroxy pinanone, as a chiral auxiliary to direct the stereoselective alkylation of the corresponding ketimine. This invention also relates to key intermediates useful in the processes referred to herein.
专利号:WO-2024258613-A9 优先权日:2023-06-16 标题:Tetrachlorovancomycin and derivatives 发明人:BOGER DALE 权利人:SCRIPPS RESEARCH INST 摘要:A total synthesis of a new class of vancomycin analogues of reduced synthetic complexity was developed. The synthesis, achieved by the addition of two aryl chloride substituents to provide tetrachlorovancomcyin aglycon (Compound II), tetrachlorovancomcyin (Compound I ), and their derivatives, permitted a streamlined total synthesis of the new class of glycopeptide antibiotics by removing atropisomer stereochemical control and enabled the simultaneous and further activated SNAr macrocyclizations that establish the tricyclic skeleton of Compound I. In addition to the antimicrobial evaluation of tetrachlorovancomycin (Compound I), the preparation of key binding pocket and peripherally-modi fied derivatives, which overcome vancomycin resistance and introduce independent and synergistic mechanisms of action, revealed their exceptional antimicrobial potency and provide the foundation for use of this new class of synthetic glycopeptide analogues. Also disclosed are a pharmaceutical composition containing bactericidal amount of tetrachlorovancomycin, a derivative thereof or a salt of either dissolved or dispersed in a pharmaceutically acceptable diluent.
专利号:US-9790171-B2 优先权日:2013-01-14 标题 :Synthesis intermediates for obtaining derivatives of sphingosines, ceramides and sphingomyelins with good yields 发明人:GUILLONEAU LOIC; DUFOUR SAMUEL; GUERRET OLIVIER 权利人:M2I DEV 摘要:The subject matter of the present invention is the novel molecules of formulae E, E′ and F. These molecules prove to be synthesis intermediates that are very advantageous for the manufacture of derivatives of sphingosine or of ceramides functionalized in position 1, with good yields, in which R 1 and R 2 are fatty chains, R 3 is an alkyl group and R 4 is a protective group for alcohol functions. Another subject of the invention is the use of the intermediates of type F for converting same into intermediates of type G, by means of reduction in the presence of lithium borohydride. The G molecules are precursors that are known to make it possible to obtain sphingolipids or sphingomyelin.
