  • UCH9, a New Antitumor Antibiotic Produced byStreptomyces. II. Structure Elucidation of UCH9 by Mass and NMR Spectroscopy.
    作者:RITSUKO KATAHIRA、YOICHI UOSAKI、HARUMI OGAWA、YOSHINORI YAMASHITA、HIROFUMI NAKANO、MAYUMI YOSHIDA
    DOI:10.7164/antibiotics.51.267

    The structure of UCH9, which is a novel antitumor agent, was determined by spectroscopic methods. UCH9 consists of an aglycone and five 2, 6-dideoxy sugars (three D-olivoses, one 4-O-methyl-D-olivose and one D-oliose). Four of the five sugars are sequentially connected through a β1→3 linkage (olivose-1→3-4-O-methyl-olivose-1→3-oliose-1→3-olivose). On the basis of the results of spectroscopic analysis, it was found that UCH9 belongs to the aureolic acid family of antibiotics. The structure of UCH9 is unique in that mono- and tetrasaccharide moieties, and a long hydrophobic side chain (sec-butyl group) are attached to the aglycone, while di- and trisaccharide moieties and a methyl or a hydrogen are attached in the case of the known aureolic acid analogs. It is known that aureolic acid analogs form a dimer in the presence of Mg2+. NMR, FAB-MS and atomic absorption analysis revealed that UCH9 isolated from Streptomyces also forms a dimer, containing one equivalent molar Mg2+
    UCH9的结构是一种新型抗肿瘤剂,通过光谱方法确定。UCH9由一个非糖部分和五种2,6-二糖组成(包括三个D-橄榄糖、一个4-O-甲基-D-橄榄糖和一个D-橄榄糖)。五种糖中有四种通过β1→3连接依次相连(橄榄糖-1→3-4-O-甲基-橄榄糖-1→3-橄榄糖-1→3-橄榄糖)。根据光谱分析的结果,发现UCH9属于黄色酸类抗生素。UCH9的结构独特,因为它的非糖部分连接了单糖和四糖基团,以及一个长的疏性侧链(叔丁基),而已知的黄色酸类类似物则连接了二糖和三糖基团以及一个甲基。已知黄色酸类类似物在存在Mg2+的情况下会形成二聚体。NMR、FAB-MS和原子吸收分析显示,从放线菌中分离的UCH9也形成了一个含有一个当量摩尔的Mg2+的二聚体。
  • Two-step synthesis of C-glycosyl juglones from unprotected sugars: a novel approach to angucycline antibiotics
    作者:Goh Matsuo、Shuichi Matsumura、Kazunobu Toshima
    DOI:10.1039/cc9960002173
    日期:——
    The two-steps synthesis of C-glycosyl juglones, versatile synthetic intermediates for angucycline antibiotics, has been developed by the C-glycosidation of naphthalene-1,5-diol with an unprotected sugar and the subsequent regioselective photooxygenation of the resultant C-glycosyl naphthalenediol.
    -1,5-二醇与未保护的糖进行C-糖基化,随后对得到的C-糖基二醇进行位点选择性光化,从而合成出两种环己烯抗生素的多功能合成中间体——C-糖苷二醇,该合成过程分为两步。
  • Synthesis of All Diastereomers of the 2-Deoxypentoses and the 2,6-Dideoxyhexoses from 2-Phenyl-1,3-dioxan-5-one Hydrate
    作者:Trond Ulven、Per H. J. Carlsen
    DOI:10.1002/1099-0690(200109)2001:17<3367::aid-ejoc3367>3.0.co;2-h
    日期:2001.9
    All diastereomers of the 2-deoxypentoses and the 2,6-dideoxyhexoses were synthesized from 2-phenyl-1,3-dioxan-5-one hydrate (1), by alkylation via the RAMP-hydrazone (2). Some of the diastereomers were synthesized in the racemic form via the dimethylhydrazone (28). The 2-deoxypentoses were synthesized by alkylation with allyl bromide, followed by stereoselective reduction, ozonolysis, and deprotection

  • Environmentally benign aryl C-glycosidations of unprotected sugars using montmorillonite K-10 as a solid acid
    作者:Kazunobu Toshima、Yasunobu Ushiki、Goh Matsuo、Shuichi Matsumura
    DOI:10.1016/s0040-4039(97)01724-3
    日期:1997.10
    Highly practical aryl C-glycosidations of unprotected 1-OMe and 1-OH sugars with phenol and naphthol derivatives were effectively realized using montmorillonite K-10 as an environmentally compatible solid acid in CHCl3 or H2O. (C) 1997 Elsevier Science Ltd.
