Chemoselective one-pot conversion of primary alcohols to their bis(indolyl)methanes promoted by Bi(NO3)3·5H 2O

Abstract

A new, "green" and efficient one-pot protocol for the synthesis of bis(indoyl)methanes from primary alcohols using Bi(NO3) 3 · 5H2O is described. This procedure performs chemoselectively through a solvent-free reaction and the products are obtained in high to excellent yields. © 2007 Verlag der Zeitschrift für Naturforschung.
