  Synthesis and pharmacological evaluation of a new series of substituted benzoyl-γ-butyrolactone derivatives

  摘要：

  A series of substituted benzoyl-gamma-butyrolactones (1-3) has been synthesized and tested for their ability to affect central dopaminergic and GABAergic function in comparison to gamma-butyrolactone (GEL). Similarly to GEL, alpha-, beta- and gamma-substituted GBLs 1-3 with one or more chlorine on the phenyl ring were found to induce central depressant effects in rats, though at different degrees. However, the test compounds modified dopamine (DA) metabolism in rat striatum differently from GEL. In fact, whereas GEL increased both DA and dihydroxyphenylacetic acid (DOPAC) content, GEL derivatives 1-3 increased DA levels, but reduced the DOPAC concentration. Moreover, some of them, unlike GEL, effectively antagonized pentylenetetrazole (PTZ)-induced seizures in mice. In particular, alpha-3,5-dichlorobenzoyl-GBL (1g) was effective at a dose as low as 36 mg/kg in decreasing the number of animals having convulsions. However, in vitro addition and in vivo administration of the test compounds failed to modify [S-35]-t-butylbicyclo-phosphorothionate ([S-35]-TBPS) binding, which is a very sensitive tool for revealing changes in the GABAergic function.

• Second-Layer Chiral Environment-Induced Steric Hindrance Enables Catalyst Conformation Lockdown in Enantioselective Hypervalent Iodine Organocatalysis

  日期：2023.6.16

  A class of confined chiral hypervalent iodines have been designed and developed by incorporating two sterically demanding BINOL-derived units, which form the second-layer chiral environment, into the iodine-containing molecules to lock down the conformation of the catalyst and indirectly create a compact chiral environment around the active site. Good-to-excellent enantioselectivities have been achieved

  通过将两个空间要求高的 BINOL 衍生单元（形成第二层手性环境）结合到含碘分子中以锁定催化剂的构象并间接产生致密结构，设计和开发了一类受限手性高价碘活性位点周围的手性环境。这些催化剂在酮的 α-氧磺酰化（高达 97.5:2.5 er）和 5-oxo-5-arylpentanoic 酸氧化环化为 γ-丁内酯（高达 98:2）方面实现了良好至卓越的对映选择性呃），从而证明了这种策略在催化剂设计中的实用性。
