ChemInform Abstract: Synthesis of β-Substituted Cyclic Enones via Phosphonium Salt-Activated, Palladium-Catalyzed Cross-Coupling of Cyclic 1,3-Diones.
ChemInform(2016)
摘要
Activation of cyclic 1,3‐diones with PyBroP generates phosphonium salt intermediates which readily undergo Pd‐catalyzed Suzuki—Miyaura coupling with boronic acids and pinacol esters as well as Pd/Cu‐catalyzed Sonogashira coupling with terminal alkynes.
