Effective synthesis of some indole nitriles from the related carbaldoximes
摘要:
Four 7-cyano-indoles and one 2-cyano-indole have been synthesized from the related aldoximes, via the intermediate 2,4-dinitrophenyl oxime ethers. (c) 2005 Elsevier Ltd. All rights reserved.

A series of macrocyclic tris(indolylmethylene) compounds (calix[3]indoles] can be obtained from 7- or 2-hydroxymethylindoles or from the combination of either an indole with a bis(hydroxymethyl)-2,7′-diindolylmethane or a bis(hydroxymethyl)indole with a 2,7′-diindolylmethane; an isomeric series can be obtained from the combination of an indole with a bis(hydroxymethyl)-2,2′-diindolylmethane.

7-nitroethylindoles is described. The 7-nitroethylindoles are converted to 2,2′-diindolylmethanes and the nitro groups reduced to amino. The resulting diamines undergo reactions with indole-2,7-dicarbaldehydes to form the macrocyclic imines, which can subsequently be reduced to the macrocyclic amines.
