  Synthesis of new ligands for targeting the S1P1 receptor

  摘要：

  Sphingosine-1-phosphate (S1P) influences various fundamental biological processes by interacting with a family of five G protein-coupled receptors (S1P(1-5)). FTY720, a sphingosine analogue, which was approved for treatment of relapsing forms of multiple sclerosis, is phosphorylated in vivo and acts as an agonist of four of the five S1P receptor subtypes. Starting from these lead structures we developed new agonists for the S1P(1) receptor. The biological activity was tested in vivo and promising ligands were fluorinated at different positions to identify candidates for positron emission tomography (PET) imaging after [F-18]-labelling. The radioligands shall enable the imaging of S1P(1) receptor expression in vivo and thus may serve as novel imaging markers of S1P-related diseases. (C) 2015 Elsevier Ltd. All rights reserved.

  立体选择性合成神经酰胺的氟化和非氟化三唑类似物

  摘要：

  对映体选择性地制备了一系列天然存在的鞘脂的非对映异构的氟化和非氟化的三唑类似物，例如二氢神经酰胺，适用于物理化学和药物化学应用。合成序列的关键步骤是α，β-不饱和酯向二醇的不对称Sharpless二羟基化，叠氮化物衍生的环状硫酸盐的区域选择性开环，炔烃与1,3-偶极环加成反应以及酯基的还原。 鞘脂-不对称合成-1,3-偶极环加成-三唑-对映选择性氟化-亲核取代

Corresponding esters derived from (Z)-2-fluorocyclododec-2-enol (22), did rearrange to yield mixtures of diastereomers much less selectively.

  1,1,3,3,3-Pentafluoropropene-diethylamine complex (PFPDEA) has been found useful as a fluoride source in halofluorination reactions of various olefins. Reactions proceeded with PFPDEA and N-halosuccinimide (NXS, X = Br, I) or 1,3-dibromo-5,5-dimethylhydantoin (DBH), as sources of electrophilic halogens, in a regioselective manner.
