- Аннотация: Efficient synthesis of CF3-functionalized 1,3-dioxolane phosphonates via base-catalyzed nucleophilic addition/cyclization of diethyl ethynylphosphonate or diethyl 3-hydroxyprop-1-yn-1-ylphosphonates with trifluoromethylketones is described. Synthesis of various CF3-substituted 1,3-dioxolane derivatives in good to excellent yields with a broad range of substrates is described.
