Synthesis of Alkenyl Diketones from Propargylic Alcohols and Anhydrides Catalyzed by Silver Perchlorate
Alkenyl diketones are important industrial materials and multifunctional organic intermediates,which have extensive applications in pharmaceutical engineering,fragrance processing and chemical synthesis.In this study,several unprecedented alkenyl diketones has been successfully synthesized for the first time,through the reaction of propargylic alcohols and anhydrides with silver perchlorate(AgClO4)as the catalyst.This solvent-free reaction process has the advantages of simple operation,mild conditions,eco-friendliness,and wide substrate scope,implying its great potential for the synthesis of alkenyl diketones.
