Damsin (1) is a pseudoguaianolide sesquiterpene possessing potent biological activities, reported as a metabolite of several medicinal plants belonging to the genus Ambrosia together with related compounds. Starting from 1, which can be isolated in good amounts from Ambrosia arborescens, the five natural pseudoguaianolides ambrosin (2), isodamsin (3), 3α-hydroxydamsin (4), 3α-acetoxydamsin (5), and 11β,13-dihydrodamsin (8) were prepared by regio- and stereo-selective synthetic modifications.
丹参素(1)是一种具有强效生物活性的假瓜子苷倍半萜,据报道它是属于伏牛花属的几种药用植物的代谢产物以及相关化合物。从 1 开始,通过区域和立体选择性合成修饰,制备出了五种天然假瓜子烯醇内酯ambrosin (2)、isodamsin (3)、3α-hydroxydamsin (4)、3α-acetoxydamsin (5) 和 11β,13-dihydrodamsin (8)。
