Indium(III) chloride catalyzed conjugate addition reaction of alkynylsilanes to acrylate esters

摘要

A novel and efficient procedure for the synthesis of δ,γ- alkynyl esters by the conjugate addition of alkynylsilanes to acrylate esters in the presence of a catalytic amount of indium(III) chloride has been developed. This method provides a rapid and efficient access to substituted δ,γ-alkynyl esters.
