One-Step Synthesis of Phosphorylated Vinylacethylene Derivatives

详细

A one-step method for the preparation of 3-substituted 2-(diethylphosphoryl)but-1-en-3-ynes was developed based on the reaction of phosphorylated α-allene alcohols with methanesulfonic anhydride in the presence of triethylamine. The obtained vinylacetylene derivatives are of interest as promising precursors for the creation of organophosphorus heterocyclic compounds.
