spectroscopic data of these semisynthetic diterpenes were identical to those given for the natural ones in the literature. These abietane diterpenes have very interesting biological activities and the semisynthetic approach described here represents an alternative to obtain them from other major diterpenes isolated from Salvia species. Additionally, seven new semisynthetic diterpene analogues, 11,14-dioxo-12,16-epoxy-8
已知的二萜12,16-环氧香茅酚(2),异丹参酮II(6)和(+)-新隐丹参酮(8)是通过16-羟基香茅酚(1)的部分合成而获得的,16-羟基香茅酚(1)是相对分离的C-16羟基化松香二萜丹参的地上部分丰富。这些半合成二萜的物理和光谱数据与文献中对天然二萜的数据相同。这些松果二萜具有非常有趣的生物学活性,此处描述的半合成方法代表了从丹参属植物中分离的其他主要二萜获得它们的一种选择。此外,七个新的半合成二萜类似物,11,14-dioxo-12,16-epoxy-8,12-abietadien-20,7beta-olide(3),11,14-dioxo-12,16-epoxy-8,12 ,15(16)-松香三烯-20,7β-内酰胺(4),15,16-didehydro-12,
