experimental part, p. 4252 - 4258 (2012/07/14)

A simple and efficient method for the synthesis of 2-(2-acylvinyl)-3-(5- alkyl-2-furyl)indoles by reductive recyclization of bis(5-alkyl-2-furyl)(2- nitroaryl)methanes is reported. This transformation was carried out by heating the substrates with SnClsu
