摘要
An efficient synthetic method for bis（indol-3-yl）alkane derivatives has been developed.In the presence of 5 mol%of pyridinium tribromide（PTB）,the condensation of indoles and aldehydes proceeded smoothly under mild conditions,giving rise to the corresponding bis（indol-3-yl）alkanes in good to excellent yields.
