Some new aplysinopsin analogues were prepared by a simple coupling of N,N-(dimethylamino)methylidene substituted hydantoin, thiohydantoin, and thiazolone derivatives, with indole derivatives. Configuration around the exocyclic CC double bond was determined on the basis of long-range heteronuclear coupling constants using 2D HMBC correlation technique.
通过将N,N-(二甲基氨基)亚甲基取代的乙内酰脲,硫代乙内酰脲和噻唑酮衍生物与吲哚衍生物简单偶联,制备了一些新的皂素类似物。基于远距离异核偶联常数,使用2D HMBC相关技术确定了环外CC双键周围的构型。
