  Trifluoroacetic Acid-Promoted Synthesis of 3-Hydroxy, 3-Amino and Spirooxindoles from α-Keto-N-Anilides

  摘要：

  Ketoanilides containing alkyl side chains were readily cyclized to 3-hydroxy-2-oxindoles or spirooxindoles by a single or double intramolecular Friedel-Crafts reaction in the presence of trifluoroacetic acid (TFA) at room temperature or at 45 degrees C. alpha-Iminocarboxamides, generated in situ from ketoamides, cyclized similarly to 3-aminooxindoles under identical conditions,

  摘要：

  3-芳基吲哚衍生物是通过Friedel-Crafts型环化合成的。该反应由三甲基甲硅烷基氰化物和Pd（OAc）2原位生成的三甲基甲硅烷基三氰基钯酸酯络合物催化。来自N-芳基扁桃酰胺的磷酸二乙酯种类繁多，几乎定量地转化为羟吲哚。当使用N，N-二苄基酰胺代替苯胺基物时，得到苯并稠合的δ-内酰胺。羟吲哚产物进行取代反应，得到具有两个不同芳基的3，3-二芳基羟吲哚。

  reaction provides an efficient route to α‐ketoamides compounds, which are ubiquitous structural units in a number of biologically active compounds. N‐substituted anilines are suitable substrates for this transformation. Two CH bonds as well as one CH and one NH bond are cleaved in this reaction. Molecular oxygen (1 atm) is used as the oxidant and the reaction involves dioxygen activation.

  copper-catalyzed reaction of alpha-azido-N-arylamides was found to proceed under an oxygen atmosphere to afford azaspirocyclohexadienones. The present transformation is carried out by a sequence of denitrogenative formation of iminyl copper species from alpha-azido-N-arylamides and their imino-cupration with an intramolecular benzene ring on the amido nitrogen followed by consecutive formation of C=O bonds.

  Friedel–Crafts-type cyclization. The reaction was catalyzed by a trimethylsilyl tricyanopalladate complex generated in situ from trimethylsilyl cyanide and Pd(OAc)2. Wide varieties of diethyl phosphates derived from N-arylmandelamides were converted almost quantitatively into oxindoles. When N,N-dibenzylamide was used instead of an anilide substrate, a benzo-fused δ-lactam was obtained. An oxindole product was subjected
