Four-component one-pot synthesis of triphenylamine-pyridine derivatives
A series of triphenylamine-pyridine derivatives were synthesized by four-component one-pot reaction of triphenylamine aldehyde, aeetophenone, 3-cyanoaeetyl indole and ammonium acetate at refluxing temperature and microwave irradiation.This method has the advantages of good yield and easy operation. The structures of the products were characterized by 1H NMR spectra, IR and elemental analysis.
