The epoxyquinone natural products SDEF 678metabolite, speciosin A, speciosin B and speciosin C have been prepared for the first time via a short synthetic route based around the palladium-catalysed coupling of a halogen-substituted 1,4-benzoquinone monoketal, a Diels–Alder/retro-Diels–Alder sequence and a diastereoselective epoxidation process.
环氧醌天然产物 SDEF 678 代谢物、speciosin A、speciosin B 和 speciosin C 首次通过基于钯催化偶联的卤素取代的 1,4-苯醌单缩酮(Diels– Alder/retro-Diels-Alder 序列和非对映选择性环氧化过程。
