  Discovery of Potent 3,5-Diphenyl-1,2,4-oxadiazole Sphingosine-1-phosphate-1 (S1P₁) Receptor Agonists with Exceptional Selectivity against S1P₂ and S1P₃

  摘要：

  A class of 3,5-diphenyl-1,2,4-oxadiazole based compounds have been identified as potent sphingosine-1-phosphate-1 (S1P(1)) receptor agonists with minimal affinity for the S1P(2) and S1P3 receptor subtypes. Analogue 26 (S1P(1) IC50 = 0.6 nM) has an excellent pharmacokinetics profile in the rat and dog and is efficacious in a rat skin transplant model, indicating that S1P(3) receptor agonism is not a component of inummosuppressive efficacy.

• Copper‐Catalyzed Chemo‐ and Enantioselective Radical 1,2‐Carbophosphonylation of Styrenes

  Copper-catalyzed chemo- and enantioselective radical 1,2-carbophosphonylation of styrenes from readily available alkyl halides and dialkyl phosphites is developed. The key to the success of the strategy lies in not only the proper choice of phosphorus reagents to suppress the reverse chemoselectivity but also the utilization of a chiral N,N,N-ligand to forge chiral C(sp3)−P bond.

  开发了铜催化的化学选择性和对映选择性自由基 1,2-碳膦酰基化苯乙烯从容易获得的烷基卤化物和亚磷酸二烷基酯。该策略成功的关键不仅在于正确选择磷试剂以抑制反向化学选择性，还在于利用手性N,N,N-配体形成手性 C(sp 3 )−P 键。

  A rhodium-catalyzed [3+2] cycloaddition reaction between readily available gem-difluorinated cyclopropanes and internal olefins has been developed, providing a wide range of multisubstituted gem-difluorinated cyclopentanes. This reaction shows an example where the “CF2” motif can be kept upon ring extension. The process is atom-economic and allows to reach numerous gem-difluorinated cyclopentanes with

  The first enantioselective allylation of indoles with gem-difluorinated cyclopropanes is developed under rhodium catalysis. The reaction shows exceptional branched regioselectivity and excellent enantioselectivity with a bulky ligand, which provides an efficient route to enantioenriched C2 and C3 fluoroallylated indoles with wide substrate scope and good functional group tolerance.
