As an extension of our earlier study, (E)-alkyl 3- (dialkoxyphosphoryl)-3-phenylacrylates were synthesized by the addition of dialkyl phosphites to the triple bond of alkyl phenylpropiolates under microwave irradiation. The (E)- diastereoselectivity of the monoadducts falls in the range of 84–90%. There was no need to use any catalyst.

Keywords: Alkyl phenylpropiolate, dialkyl phosphite, addition, microwave.
