Salvilenone 1, a phenalenone diterpene isolated from the roots of Salvia miltiorrhiza Bunge, was synthesized in thirteen steps from resorcinol dimethyl ether. Dihydrophenalenol derivative 19, a key intermediate, was treated with aqueous hydrobromic acid to give salvilenone accompanied by the formation of a hydroxy diketone 20.
从丹参(Salvia miltiorrhiza Bunge)根部分离出的酚烯酮二萜--沙维烯酮 1 是由间苯二酚二甲醚经 13 个步骤合成的。二氢苯亚酚衍生物 19 是一种关键的中间体,经氢溴酸水溶液处理后可得到沙维烯酮,同时形成羟基二酮 20。
