  异吲哚啉酮的串联 C(sp3)−H 芳基化/氧化和芳基化/烯丙基取代

  摘要：

  异吲哚酮包含一类重要的药用活性化合物。在此，我们报告了使用乙酸钯 (II)/NIXANTPHOS 基催化剂系统对异吲哚啉酮与芳基溴化物进行直接官能化（22 个示例）。此外，还可以通过串联反应获得具有抗肿瘤活性的 3-芳基-3-羟基异二氢吲哚酮衍生物。因此，当芳基化产物在碱性条件下暴露于空气时，会发生原位氧化以安装3-羟基。此外，进行串联芳基化/烯丙基取代反应，其中芳基化和烯丙基取代均由相同的钯催化剂催化。最后，提出了串联芳基化/烷基化程序。这些串联反应使得能够从常见的起始材料合成各种结构不同的异吲哚酮衍生物。

• BMIm HCO₃: an ionic liquid with carboxylating properties. Synthesis of carbamate esters from amines
  作者：A. Di Nicola、A. Arcadi、L. Rossi

  日期：——

  1-Butyl-3-methylimidazolium hydrogen carbonate (BMIm HCO3) was used as an ionic liquid with carboxylating properties able to convert, in the presence of an alkyl halide, amines into the corresponding carbamate esters. Moderate to good yields of carbamates were obtained according to the nature of the amine and the alkylating agent.

• Electrogenerated Superoxide-Activated Carbon Dioxide. A New Mild and Safe Approach to Organic Carbamates

  The electrochemical reduction of O-2 (E = -1.0 V vs SCE) in dipolar aprotic solvents in the presence of CO2 gave a carboxylating reagent (O-2(.-)/CO2) able to convert amines and different types of their derivatives into carbamates. Primary and secondary aliphatic and aromatic amines were converted into the corresponding ethyl carbamates by the addition of EtI to the carbamate anions generated in the first step of the reactions. The yields were dependent on the nucleophilicity of the nitrogen atom. beta-Bromoethyl- and propylamine gave 2-oxazolidinone and tetrahydro-1,3-oxazin-2-one in moderate yields. N-Acyl or N-(alkoxycarbonyl)alkylamines bearing a leaving group at the beta position of the alkyl substituent were converted into 3-substituted-2-oxazolidinones in high yields. By using chiral substrates, enantiopure 3-alkoxycarbonyl(or acyl)-4-substituted oxazolidin-2-ones (70-85% isolated yields) were obtained. This represents a new mild and safe route to these important auxiliaries for asymmetric synthesis. Some limitations of the process are also evidenced and accounted for.
