The bioactivity-directed isolation and structural determination of β-miroside 3-[(β-D-glucopyranosyloxy)-methyl]-2(5H)-furanone} from the New Zealand gymnosperm Prumnopitys ferruginea, is described. Picein 4-(β-D-glucopyranosyloxy)acetophenone} was also isolated. Syntheses of β-miroside, its α-anomer and an isomer with an exocyclic double bond, are described, along with an unusual reaction of an
描述了从新西兰裸子植物Prumnopitys ferruginea提取的β-紫罗兰苷3-[(β-D-吡喃葡萄糖基氧基)-甲基] -2(5H)-呋喃酮}的生物活性指导的分离和结构测定。还分离出Picein 4-(β-D-吡喃葡萄糖基氧基)苯乙酮}。描述了β-多侧面苷,其α-端基异构体和具有环外双键的异构体的合成,以及环外烷氧基亚烷基内酯与N-溴代琥珀酰亚胺的不寻常反应,得到具有环内双键的产物。β-Miroside具有抗真菌,抗菌和细胞毒活性。
