Abstract: A series of (E)-β-(alkoxy)arylethylenes was synthesized by the one-pot three-component reaction of substituted benzyl alcohol, dimethyl sulfoxide and alkyl alcohols under mild conditions. This method has the advantages of high yields(68%~82%) and simple workup. The structures of the products were identified by 1H NMR, 13C NMR spectra and elemental analysis. In addition, the probable mechanism for the reaction was proposed.

Key words: three-component one-pot, (E)-beta-(alkoxy)styrenes, benzyl alcohol, dimethyl sulfoxide, synthesis
