  Base-Mediated Intramolecular Decarboxylative Synthesis of Alkylamines from Alkanoyloxycarbamates

  摘要：

  A general and effective method for the synthesis of alkylamine via intramolecular decarboxylation of alkanoyloxycarbamates is described. The alkanoyloxycarbamates are readily prepared with alkyl carboxylic acids and hydroxylamine. The reaction shows a broad range of substrates (primary and secondary alkyl) with functional tolerance, and the corresponding products were obtained in good yields under mild conditions.

  [reaction: see text] Room-temperature reduction of aromatic nitro groups to amines can be accomplished in high yield, with wide functional group tolerance and short reaction times (30 min) using a combination of palladium(II) acetate, aqueous potassium fluoride, and polymethylhydrosiloxane (PMHS). Replacing PMHS/KF with triethylsilane allows aliphatic nitro groups to be reduced to their hydroxylamines.

  A combination of palladium(II) acetate, aqueous potassi- um fluoride, and polymethylhydrosiloxane (PMHS) facilitates the room-temperature reduction of aromatic nitro compounds to anilines. These reactions tend to be quick (30 min), high-yielding, and tolerate a range of other functional groups. Replacement of PMHS/KF with triethylsilane allows for the reduction of aliphatic nitro compounds to their

  醋酸钯 (II)、氟化钾水溶液和聚甲基氢硅氧烷 (PMHS) 的组合有助于在室温下将芳香族硝基化合物还原为苯胺。这些反应往往快速（30 分钟）、高产，并且可以耐受一系列其他官能团。用三乙基硅烷代替 PMHS/KF 可以将脂肪族硝基化合物还原为相应的羟胺。根据底物的不同，这两种条件都可以将产物胺原位转化为酰胺、磺酰胺和氨基甲酸酯。
