(6), galdosol (7), and epirosmanol (8) have been obtained by partial synthesis from carnosol (2), an abundant natural product present in Salvia species. The physical and spectroscopic data of these semisynthetic diterpenes were identical to those of authentic natural samples and with data reported in the literature. These abietane diterpenes have very interesting biological activities and are present
已知的二萜rosmanol(3),rosmaquinone(4),7-甲氧基rosmanol(5),7-ethoxyrosmanol(6),galdosol(7)和epirosmanol(8)是由鼠李糖酚(2),丹参物种中存在丰富的天然产物。这些半合成二萜的物理和光谱数据与真实的天然样品的数据相同,文献报道的数据也相同。这些松果二萜具有非常有趣的生物学活性,并以少量存在于丹参中。因此,本文所述的半合成方法代表了一种获得这些化合物的有效替代方法。此外,通过与Ph3P / NBS在CH2Cl2中反应,从16-羟基香茅醇(9)获得了已知的二萜16-羟基香豆酚(10)和新的芳族二萜11。
