A facile diastereoselective synthesis of panduratin A derivatives using commercially available aluminum(III) bromide is reported. The effect of substituents on the Diels–Alder reaction of various trans -chalcones with ( E )-ocimene was investigated. A series of panduratin A derivatives were prepared in moderate to good yields.
报道了使用市售的溴化铝 (III) 对潘多汀 A 衍生物进行简便的非对映选择性合成。研究了取代基对各种反式查耳酮与 (E)-罗勒烯的 Diels-Alder 反应的影响。以中等至良好的产率制备了一系列潘多汀 A 衍生物。
