Reactions of 2-(Lithiomethyl)phenyl Isocyanides with Methyl 1-Methylindole-3-carboxylate: Flaborations of the Adducts to 5H-Benz[2,3]azepino[5,6-c]indol-12-one and 2,3’-Biindolyl Derivatives
摘要:
It has been found that when 2-(lithiomethyl)phenyl isocyanides were allowed to react with methyl 1-methylindole-3-carboxylate, the corresponding 1,4-and/or 1,2-adducts were obtained. The 1,4-adducts could be transformed into 6,11-dihydro-5H-benz[2,3]azepino[5,6-b]indol-12-ones derivatives by acid hydrolysis, followed by lactamization and subsequent dehydrozgenation. The transformation of the 1,2-adducts into 2,3'-biindolyls was accomplished by a sequential treatment with hydrochloric acid and aqueous sodium hydroxide.

A general and selective method has been achieved to synthesize 2,3'- biindolyls and 2,2'-indolylpyrroles through an acid catalysed reaction of 3-bromoindoles with indoles or pyroles. I.R., 1H-NMR, 13C-NMR and MS data of the dimers are also reported.

The 3-bromoindoles were found to react with pyrroles and indoles, in the presence of protic or Lewis acids, to give 2-(2-indolyl)pyrroles, 2,3′-bi-indolyls, and trimetic products such as 2-(3-indolyl)-3-(2-indolyl)indoles.
