  Rapid Route to 3,4-Substituted Indoles via a Directed Ortho Metalation−Retro-Mannich Sequence

  摘要：

  [GRAPHICS]In the presence of NXS (X = Br, I, Cl), gramine derivatives 1, derived by combined directed ortho metalation (DoM)-cross-coupling sequences, rapidly undergo retro-Mannich fragmentation (2) to afford 3-halo indoles 3 in 37-88% yields. A conceptually new methodology to diverse 3,4-substituted indoles (10, 11, 13) is thereby introduced.

• Intramolecular [3 + 2]cycloadditions: synthesis of 1-methylene-2,3,3a,4,5,9b-hexahydro-1H-benz[e]indenes and an unsuccessful approach to ergot alkaloids

  3-enyl)-4-methoxybenzenes, prepared by a short synthesis, underwent intramolecular [3 + 2]cycloadditions to produce the title indenes. An analogous intramolecular cycloaddition was attempted with N-benzyl-4-(2-methoxyvinyl)-3-(2-hydroxy-3-trimethylsilylmethylbut-3-enyl)indoline, in an attempt to produce a key intermediate for ergot alkaloid synthesis, but this was unsuccessful.

  Various 4-halogeno-3-indoleacetic acids and -3-indoleacetonitriles were synthesized for the first time by means of the Sandmeyer or Schiemann reaction, demonstrating the versatility of 4-indolediazonium salts in 4-substituted indole chemistry. A practical synthetic method for 4-halogenoindoles was developed by regio-selective thallation-halogenation, and the products were also led to 4-halogeno-3-indoleacetic acids. The first synthesis of 4-formyl-3-indoleacetonitrile is also reported.

  Lithiation of 1-alkoxyindoles, 3-dimethylaminomethyl- and 3-dimethylaminoethyl-1-methoxyindole occurred regioselectively at the 2-position. The introduction of a sterically bulky group into the 2-position of 3-dimethylaminomethyl-1-methoxyindoles directed the lithiation to the 4-position.
