  • Process for the preparation of tetrahydropyran derivatives
    申请人:Nisshin Pharma Inc.
    公开号:US06339162B1
    公开(公告)日:2002-01-15
    A process of making arbutin and its derivatives comprises solvolyzing an acylated precursor of arbutin or its derivative in a solution comprising an organic solvent and a base, neutralizing the solution with an acid, and crystillizing the product arbutin or its derivative. The process may be employed on an industrial scale and avoids the use of ion exchange columns. The process has the advantages of not requiring ion exchange columns and peripheral devices, which leads to cost and time savings, due to the elimination of column regeneration steps. Waste water from column regeneration is also eliminated.

    日期:2019.8.2
    We describe a palladium-catalyzed chemoselective Negishi cross-coupling of a bis[(pinacolato)boryl]methylzinc halide with aryl (pseudo)halides. This reaction affords an array of benzylic 1,1-diboronate esters, which can serve as useful synthetic handles for further transformations. The developed coupling reaction is compatible with various functional groups and can be easily scaled up. The coupling

  • 一种糖苷及其衍生物的制备方法
    申请人:陕西岳达德馨生物制药有限公司
    公开号:CN110903333A
    公开(公告)日:2020-03-24
    本发明公开了一种糖苷及其衍生物的制备方法。在该方法中,将糖分子结构上的所有羟基乙酰化,同时制备含酚羟基的配体,然后以三氟化硼‑乙醚为催化剂这两者缩合得到四乙酰化糖苷,最后再脱去乙酰保护基团得到所需糖苷。该方法可以选择性催化单糖的半缩醛羟基与羟基反应得到糖苷,产物单一。该方法生产操作简单,设备要求低,可用于具有相似结构的糖苷及其衍生物的合成,绿色环保,可大规模进行生产。
