  一种新型可回收的一氧化硫转移试剂。

  摘要：

  [反应：请参见文字]。由二硫化物9通过还原成相应的二硫醇并随后用亚硫酰氯捕获而制备了三硫化物2-氧化物11。在二烯存在下加热三硫化物氧化物11导致一氧化硫以良好的至极好的收率转移形成环状不饱和亚砜13，同时回收二硫化物9。可以使用Pummerer反应将环状亚砜转化为噻吩。

  followed by in situ trapping by diene. Transfer of SO also occurs upon irradiation at room temperature, but yields of sulfoxide are lower. Dehydration of the sulfoxides under Pummerer conditions gives thiophenes, including the naturally occurring thioperillene. Two dienes form thiophenes directly under the SO transfer conditions. The methodology is applied in a formal synthesis of the antiplatelet medication

  通过用亚硫酰氯和吡啶处理 1,8-萘二硫醇制备了三个环取代的三硫化物-2-氧化物。1,2,3-trithiane-2-氧化物环在固态下采用沙发构象，具有假轴氧和环应变的证据（周边相互作用）。在二烯存在下加热三硫化物-2-氧化物会导致正式的一氧化硫 (SO) 转移形成不饱和环状亚砜，以及可回收的 1,8-萘二硫化物。萘环上邻甲氧基或邻叔丁基取代基的存在降低了温度并增加了 SO 转移发生的速率。捕获实验和动力学研究与三线态 SO 的产生一致，然后是二烯的原位捕获。SO 的转移也发生在室温下辐照时，但亚砜的收率较低。在Pummerer 条件下，亚砜脱水得到噻吩，包括天然存在的硫紫杉烯。两种二烯在 SO 转移条件下直接形成噻吩。该方法应用于抗血小板药物波立维的正式合成。

  Piperine activates TRPV1 (transient receptor potential vanilloid type 1 receptor) receptors and modulates gamma-aminobutyric acid type A receptors (GABA(A)R). We have synthesized a library of 76 piperine analogues and analyzed their effects on GABA(A)R by means of a two-microelectrode voltage-clamp technique. GABA(A)R were expressed in Xenopus laevis oocytes. Structure-activity relationships (SARs) were established to identify structural elements essential for efficiency and potency. Efficiency of piperine derivatives was significantly increased by exchanging the piperidine moiety with either N,N-dipropyl, N,N-diisopropyl, N,N-dibutyl, p-methylpiperidine, or N,N-bis(trifluoroethyl) groups. Potency was enhanced by replacing the piperidine moiety by N,N-dibutyl, N,N-diisobutyl, or N,N-bistrifluoroethyl groups. Linker modifications did not substantially enhance the effect on GABA(A)R. Compound 23 [(2E,4E)-5-(1,3-benzodioxol-5-yl)-N,N-dipropyl-2,4-pentadienamide] induced the strongest modulation of GABA(A) (maximal GABA-induced chloride current modulation (IGABA-max = 1673% +/- 146%, EC50 = 51.7 +/- 9.5 mu M), while 25 [(2E,4E)-5-(1,3-benzodioxol-5-yl)-N,N-dibutyl-2,4-pentadienamide] displayed the highest potency (EC50 = 13.8 +/- 1.8 mu M, IGABA-max = 760% +/- 47%). Compound 23 induced significantly stronger anxiolysis in mice than piperine and thus may serve as a starting point for developing novel GABA(A)R modulators.
