Abstract

L'invention concerne un procédé pour la préparation de composés de la formule (I) dans laquelle R?1¿ = H, alkyle C¿1?-C¿6?, alcényle C¿1?-C¿6?, cycloalkyle C¿3?-C¿6? ou bien phényle, et R?2¿ = H ou alkyle alkyle C¿1?-C¿3?. Dans ce procédé, on fait réagir du propyne avec un composé de la formule (II), dans laquelle R?1¿ et R?2¿ ont les significations précitées, en présence d'un système catalyseur à métal de transition.
