a particular type of sesquiterpene lactones, were synthesized from the commercially available α-santonin (11) using a facile strategy involving a high-yielding photochemical reaction. Natural products 10 and 17 from Artemisia gorgonum were synthesized in good yields. Specifically, compound 10 was obtained in five steps with an overall yield of 17%. The sesquiterpene lactones were tested in the etiolated
使用一种涉及高产光化学反应的简便策略,由市售的α-桑顿宁(11)合成11,13-脱氢癸二酚内酯,一种特殊的倍半萜烯内酯。来自蒿的天然产物10和17以高产率合成。具体地,以五个步骤获得化合物10,总产率为17%。倍半萜内酯在黄化的小麦胚芽鞘生物测定中进行了测试,活性最高的化合物在标准目标物种上进行了测定。与已知的除草剂Logran相比,瓜亚胺内酯13具有最高的植物毒性活性。
