One-Pot Synthesis of 1,3-Diketones from Alkynones with the Assistance of Imidazole

Abstract

An efficient one-pot synthesis of 1,3-diketones has been synthesized starting from alkynones using a Michael addition–nucleophilic substitution reaction process. The reaction starts with the Michael addition of imidazoles to alkynones, followed by the nucleophilic substitution by water. The final product 1,3-diketones were characterized by the NMR spectra. This study demonstrated that such reactions could successfully occur in one pot under mild conditions with a high yield of 1,3-diketones from 65 to 93%.
