    杯红霉素 A:不对称总合成和结构测定
    摘要:
    我们报告了杯红霉素 A 的第一个不对称全合成和结构测定。利用模块化策略,开发了一种简洁的方法来组装具有内酯 A 环的两种对映异构体的六环骨架。立体选择性糖基化将有角的六环框架与单糖片段偶联以产生杯红霉素 A 及其立体异构体。这使我们能够确定和分配 C-25 (25S) 和单糖(l-葡萄糖的衍生物)的绝对构型。

    Abstract Prosapogenin was obtained by alkaline hydrolysis of Gleditsia saponin GS-C (echinoeystic acid 3, 28-O-bisdesmoside), a new triterpenoid saponin isolated from Gleditsia japoinica. Prosapogenin was shown on the basis of chemical and physicochemical data to be echinocystic acid 3-O-β- d -xylopyranosyl-(1–2)-α- l -arabinopyranosyl-(1–6)-β- d -glucopyranoside.
    摘要 Prosapogenin 是通过皂苷 GS-C(棘皮酸 3, 28-O-bisdesmoside)碱水解获得的,该皂苷是从皂角中分离得到的一种新的三萜皂苷。根据化学和物理化学数据显示,前皂苷元是棘囊酸 3-O-β-d-吡喃木糖基-(1-2)-α-l-阿拉伯吡喃糖基-(1-6)-β-d-吡喃葡萄糖苷。

    GC-FID and GC-MS analyses of methyl derivatives, MALD-TOF-MS measurements and NMR spectra were used to confirm the structural characteristics of the isomers. The (1)H and (13)C NMR signals of each isomer saccharide were assigned using COSY, E-HSQC, HSQC-TOCSY, HMBC and H2BC techniques. These kestose isomers were identified as α-D-fructofuranosyl-(2- > 2)-α-D-glucopyranosyl-(1 < ->2)-β-D-fructofuranoside

    Three triterpenoid saponins were isolated from legumes of Gleditsia japonica cv.'Saponifera'(Leguminosae). These saponins are rare examples of triterpenoid saponins containing monoterpenes. The desmonoterpenyl compound, C74H120O38, [α]23D -42.3°(MeOH), which was obtained from them by alkali hydrolysis with K2CO3, was characterized as a 3, 28-O-bisglycoside on the basis of physical data and degradation products.
