  描述：

  2-(5-cholesten-3β-yloxy)ethyl iodide 在 吡啶 、 sodium methylate 、 溶剂黄146 、 苯基锂 、 三乙胺 、 sodium iodide 作用下， 以 1,4-二氧六环 、 甲醇 、 二氯甲烷 、 丁酮 为溶剂， 反应 60.0h， 生成 2-((6-((10,13-dimethyl-17-(6-methylheptan-2-yl)-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-3-yl)oxy)hex-3-yn-1-yl)thio)-6-methyltetrahydro-2H-pyran-3,4,5-triol

  Glycolipids as potential immunologic adjuvants

  摘要：

  A group of 1-thio-beta-L-fucopyranosides containing hexadecane, 9-octadecene, adamantane, 1,2-diphenyltetrafluoroethane, and 3-hexynyl- and 3,6-dioxaoctylcholesterols were synthesized as potential immunologic adjuvants. Many of these fucosyl lipids and 6-(5-cholesten-3 beta-yloxy)hexyl 1 thioglycosides were found to give good response to subunit A/Victoria influenza virus. Carbohydrates with L-fucose and D-galactose backbones appeared essential for adjuvant activity. Lactose which has a terminal D-galactose moiety was found to be active, whereas L-arabinose which lacks a 5-(hydroxymethyl) group was inactive.
