The synthesis of 7-tryptamines was accomplished via the reduction of 7-nitrovinylindoles which were developed by the condensation of indole-7-carbaldehydes with nitromethane and ammonium acetate. 7-Tryptamines were subsequently used for the construction of 2,3-disubstituted and 3 -substituted 7,7'-linked-bis-indoles.

A ring closing metathesis approach has been used to prepare a novel range of indoles 1,7-annulated with nitromethyl and lactone functionalised medium-sized rings. Initial studies into the preparation of lactam functionalised rings are also discussed. (C) 2011 Elsevier Ltd. All rights reserved.

The synthesis of 7-aminoacetylindoles was achieved via the hydrogenation of 7-acylcyanides, which were produced through the oxidation of indole-7-cyanohydrin silylether intermediates. 7-Oxotryptamines were subsequently converted into 5-(7'-indolyl)oxazoles by reaction with acetic anhydride followed by phosphoryl chloride, and to 2,5-di-(7'-indolyl)oxazoles by reaction with 7-trichloroacetylindoles followed by phosphoryl chloride.
