The reaction of (N-isocyanimino) triphenylphosphorane with (E)-3-aryl-2- propenoic acid derivatives: One-pot synthesis of 2-[(E)-2-aryl-1-ethenyl]-1,3,4- oxadiazoles via intramolecular aza-Wittig reaction

چکیده مقاله

The reaction of (E)-3-aryl-2-propenoic acid derivatives with (N-isocyanimino) triphenylphosphorane proceeds smoothly at room temperature to afford the corresponding 2-[(E)-2-aryl-1-ethenyl]-1,3,4-oxadiazole via an intramolecular aza-Wittig reaction in good yields under neutral conditions. The structures of the products were deduced from their IR, ¹H NMR, and ¹³C NMR spectra and mass spectrometry. Copyright © 2011 Wiley Periodicals, Inc.
