  • Conversion of Spirostane and Solanidane into Pregnane (1)Introduction of Oxygen Function into C-23
    作者:Nodoka Nakata、Asami Tokudome、Hiroyuki Yanai、Toshihiro Nohara
    DOI:10.1248/cpb.60.150
    日期:——
    A spirosolane derivative possessing a hydroxyl group at C-23, esculeogenin A, a sapogenol of tomato saponin, was found to be easily converted into the corresponding pregnane derivative by refluxing with aqueous pyridine. Therefore, introduction of a hydroxyl group into the C-23 of diosgenin (as representative of spirostane derivatives) and solasodine (as representative of spirosolane derivatives) was attempted by the reaction of NaNO2–BF3 · Et2O. In diosgenin, the objective compound was obtained by the reaction in AcOH. However, in solasodine, we obtained a 23-nitroso derivative by the reaction in AcOH and 23,24-bisnorcholanic acid 22-16 lactone, or vespertilin, in AcOH and CHCl3.
    一种具有羟基的螺烯衍生物,23位羟基的艾斯库尔根素A,作为西红柿皂苷的皂苷醇,发现其在水相吡啶回流下易于转化为相应的孕烷衍生物。因此,尝试通过NaNO2–BF3·Et2O反应将羟基引入地奥基醇(作为螺烷衍生物的代表)和索拉索丁(作为螺烯衍生物的代表)的C-23位。在地奥基醇中,目标化合物通过在醋酸中反应获得。然而,在索拉索丁中,我们通过在醋酸中的反应获得了23-亚硝基衍生物,以及在醋酸和氯仿中的反应获得了23,24-双诺基胆酸22-16内酯,或称为蝙蝠素。
  • Peculiar side-chain fission of steroidal glycosides

    日期:2003.4
    The characteristic novel steroidal glycosides of the 23,26-oxygenated spirostanol-type and 16,22-dicarbonyl cholestanol-type obtained in our laboratory underwent the peculiar reactions of side-chain fission between C-22 and C-23 of the steroidal skeleton by acid or alkaline hydrolysis. These reactions would be applied to the structural determination of these sorts of glycosides and suggest the biogenetic
    在我们实验室获得的23,26-氧化的螺固醇型和16,22-二羰基胆固醇型的新型甾体糖苷经历了甾体骨架的C-22和C-23之间的侧链裂变的奇特反应酸或碱水解。这些反应将用于这些种类的糖苷的结构测定,并提示发生C-22内酯型糖苷的生物遗传途径。
  • Synthesis of vespertilin conjugates with OSW-1 disaccharide blocks
    作者:Z. R. Valiullina、L. S. Khasanova、F. A. Gimalova、N. K. Selezneva、L. V. Spirikhin、M. S. Miftakhov
    DOI:10.1134/s1070428014100194
    日期:2014.10
    The reaction of vespertilin with 2-O-acetyl-3,4-bis-O-(triethylsilyl)-alpha-l-arabinopyranosyl trichloroacetimidate gave the corresponding glycoside. Removal of the silyl protecting group from the latter and glycosylation of the resulting diol with trichloroacetimidate derived from D-xylose afforded 3,4-regioisomeric glycosides containing OSW-1 disaccharide blocks.

  • Synthesis and plant growth promoting activity of dinorcholanic lactones bearing the 5α-hydroxy-6-oxo moiety
    作者:Anielka Rosado-Abón、Guadalupe de Dios-Bravo、Rogelio Rodríguez-Sotres、Martín A. Iglesias-Arteaga
    DOI:10.1016/j.jsbmb.2012.10.007
    日期:2013.3
    The naturally occurring dinorcholanic lactone vespertilin and two other non-natural derivatives bearing the 5α-hydroxy-6-oxo moiety were synthesized starting from the readily available steroid sapogenin diosgenin. The obtained compounds showed plant growth promoting activity in the bean's second internode elongation assay.
