(Poly)glycerol monoethers were synthesized in good yield and selectivity by the catalytic reductive alkylation of glycerol, diglycerol, and triglycerol with readily available, cheap and/or bio‐sourced carboxylic acids. The reaction was catalyzed by 1 mol % of Pd/C under 50 bar H2 using an acid ion‐exchange resin as a recyclable cocatalyst. The catalytic system was recycled several times, and a mechanism
(聚)甘油单醚是通过甘油,二甘油和三甘油与现成的廉价和/或生物来源的羧酸的催化还原烷基化反应而合成的,具有良好的收率和选择性。使用酸性离子交换树脂作为可循环助催化剂,在50 bar H 2下以1 mol%的Pd / C催化反应。催化系统被回收了几次,并提出了这种转化的机理。

The present invention relates to compounds with an increased in vivo biological activity, and especially an increased pharmaceutical activity, such as an anti-nematodal or antifungal activity, an immunosuppresive activity, a metabolism influencing activity and/or an anti-cancer activity. Specifically, the present invention relates to compound comprising an artemisinin derivative according to the general formula (I) covalently linked at the 1 or the 2 position to a compound with a biological activity thereby increasing the biological activity of said compound or a pharmaceutically acceptable salt thereof.

An object of the present invention is to provide a coated solid preparation applicable to a one-dose pack, wherein, even when the preparation is in an unpacked state, the stability against moisture of valproic acid or a pharmacologically acceptable salt thereof contained therein is maintained and the deliquescence is suppressed. The present invention provides a coated solid preparation which contains as an active ingredient valproic acid or a pharmacologically acceptable salt thereof and is coated with a coating layer containing polyvinyl alcohol and swelling clay, wherein the mass ratio of the polyvinyl alcohol to the swelling clay is 8:2 to 3:7 and the swelling clay is dispersed as a laminated structure.
