  摘要：

  AbstractStarting from 17‐hydroxyoleic acid, which is readily available from acid alcoholysis of sophorolipids, several new polyhydroxy fatty acids have been synthesized. These compounds contain from 2 to 4 hydroxy groups, in some instances combined with other functional groups. The added hydroxy groups can be incorporated in the C18 chain in a variety of geometries, for example spaced widely throughout the chain at C1, C8, and C17. This regiochemical control will be of use in structure/function studies involving materials constructed from these hydroxy fatty acids. A further benefit is that the hydroxy groups can be present in protected or free states. The principal reactions used to introduce extra hydroxy groups are selenium oxide‐mediated allylic hydroxylation, osmium‐catalyzed dihydroxylation, and borohydride reduction of a carboxylic ester. These new compounds are expected to be of use in a number of areas, but particularly as building blocks for polymers or components of lubricant formulations.

  Complete Stereocontrol in the Synthesis of Harmonine and Novel Analogues Facilitated by a Grubbs Z-Selective Cross-Metathesis Catalyst

  摘要：

  (R)-Harmonine 是以 Z 选择性交叉甲基化反应为核心，通过六步顺序合成的，总收率为 15%。通过这种策略，目标物中的顺式烯烃可以被完全安装。使用醇和酯作为胺前体对于从自甲氧基化产物中分离出交叉甲氧基化产物至关重要。这种方法还被用于制备两种新型的哈蒙德碱类似物。

  The oil formed during fermentation by a strain of Torulopsismagnoliae consisted mainly of partly acetylated 2-O-β-D-glucopyranosyl-D-glucopyranose units attached β-glycosidically to 17-L-hydroxyoctadecanoic and 17-L-hydroxy-9-octadecenoic acids.

  在Torulopsis magnoliae菌株发酵过程中形成的油主要由部分乙酰化的2-O-β-D-葡萄糖吡喃基-D-葡萄糖吡喃糖单元组成，以β-糖苷键连接到17-L-羟基十八烷酸和17-L-羟基-9-十八烯酸上。
