    Modifications of the alkyl acetic acid portion and the phenyl on pyrrolidine in our lead pyrazole compound 1 afforded the isopropyl compound 9. This compound is a potent CCR5 antagonist showing good in vitro antiviral activity against HIV-1, an excellent selectivity profile, and good oral bioavailability in three animal species. During this investigation, a new method for the preparation of alpha-
    在我们的吡唑化合物先导化合物1中烷基乙酸部分和吡咯烷上的苯基进行修饰,得到异丙基化合物9。该化合物是有效的CCR5拮抗剂,对HIV-1表现出良好的体外抗病毒活性,出色的选择性和良好的口服性三种动物的生物利用度。在该研究过程中,发现了一种新的方法,该方法使用三氟甲磺酸银从吡咯烷和α-溴-α-α,二烷基乙酸制备α-(吡咯烷-1-基)-α,α-二烷基乙酸。这使我们能够首次制备诸如24和25之类的化合物。还没有发现新型的Pd介导的α-(吡咯烷-1-基)乙酸的N-去烷基化反应。

  • PROCESS FOR PRODUCTION OF OPTICALLY ACTIVE 2-HALOGENO- CARBOXYLIC ACIDS
    申请人:KANEKA CORPORATION
    公开号:EP1481960A1
    公开(公告)日:2004-12-01
    The invention provides processes for producing efficiently optically active 2-halogenocarboxylic acids useful in the preparation of drugs or the like and salts thereof with amines. Specifically, an optically active 2-halogenocarboxylic acid is produced by halogenating an optically active amino acid in water in the presence of a hydrophobic organic solvent and nitrous acid with the configuration retained and with the racemization inhibited through the removal of 2-hydroxy- bromocarboxylic acid formed as a by-product; the obtained optically active 2-halogenocarboxylic acid is transferred to an aqueous phase by converting it into a salt thereof with a base, followed by the removal of the organic phase; and the optically active 2-halogenocarboxylic acid is transferred again to an organic solvent phase, followed by the removal of the aqueous phase, whereby an optically active 2-halogenocarboxylic acid is obtained through the removal of a halogen component. Further, a high-quality salt of an optically active 2-halogenocarboxylic acid with an amine can be obtained by a crystallization method wherein the amine is added over the period of 1/2 hour or longer either continuously or in portions and/or wherein the crystallization solvent consists of a hydrophobic organic solvent and a hydrophilic organic solvent.
    本发明提供了生产高效光学活性 2-卤代羧酸的工艺,这种 2-卤代羧酸可用于制备药物 或类似药物及其与胺的盐。具体地说,在疏水性有机溶剂和亚硝酸的存在下,通过在水中卤化光学活性氨基酸来生产光学活性 2-卤代羧酸,并保留其构型,通过去除副产物 2-羟基溴羧酸来抑制其外消旋化;将得到的具有光学活性的 2-卤代羧酸用碱转化为盐,转移到水相中,然后去除有机相;将具有光学活性的 2-卤代羧酸再次转移到有机溶剂相中,然后去除水相,这样就通过去除卤素成分得到了具有光学活性的 2-卤代羧酸。此外,光学活性 2-卤代羧酸与胺的高质量盐可通过结晶方法获得,其中胺的添加时间为 1/2 小时或更长,可连续添加或部分添加,以及/或结晶溶剂由疏水性有机溶剂和亲水性有机溶剂组成。
