Abyssinone-Ⅴ, 4'-hydroxy-6,3',5'-triprenylisoflavonone, abyssinone-Ⅵ和abyssinone-Ⅳ都是从刺桐中分离出来的天然双异戊烯基黄酮. 利用简单、温和的方法首次完成了这4个天然产物的全合成. 初步活性测试表明, 4个化合物都具有一定的抑菌活性, 其中, abyssinone-Ⅳ和abyssinone-Ⅴ对金黄葡萄球菌和大肠杆菌都有良好的抑菌效果. 所有新化合物的结构都经过HRMS, 1H NMR和13C NMR确认.

Abyssinone-Ⅴ, 4'-hydroxy-6,3',5'-triprenylisoflavonone, abyssinone-Ⅵ and abyssinone-Ⅳ were all isolated from the genus erythrina. This study completed the first total synthesis of four natural prenylated flavanoids by using simple and facile approaches. The result of their in vitro antibacterial tests indicated that all of them displayed moderate bacteriostatic activities. The compounds abyssinone-Ⅳ and abyssinone-Ⅴ showed remarkable antibacterial activities. The structures of all new compounds have been confirmed by HRMS, 1H NMR and 13C NMR spectra.
