    Since their isolation almost 20 years ago, the callipeltosides have been of long standing interest to the synthetic community owing to their unique structural features and inherent biological activity. Herein we present our full research effort that has led to the synthesis of these molecules. Key aspects of our final strategy include 1) synthesis of the C1–C9 pyran core (5) using an AuCl3‐catalysed
    自从近 20 年前被分离出来以来,卡利佩尔托苷由于其独特的结构特征和固有的生物活性,长期以来一直引起合成界的兴趣。在此,我们展示了我们合成这些分子的全部研究成果。我们最终策略的关键方面包括 1)使用 AuCl 3催化环化合成 C1–C9 吡喃核心 ( 5 );2) 通过顺序双向 Stille 反应形成 C10–C22 碘乙烯 ( 55 ),3) 通过烯基锌加成(C9 处的 dr=91:9)对这些高级片段进行非对映选择性结合。常见的 callipeltoside 苷元 ( 4 ) 在另外五个步骤中完成。此后,添加所有三个糖片段以提供整个卡利佩托苷家族。除此之外,还合成了D构型的卡利佩尔托糖 B,并将其附加到卡利佩尔托苷苷元上。发现该分子的1 H NMR谱与天然分离物显着不同,进一步支持了我们对 callipeltoside B ( 2 ) 的认定。
  • Effects of Olefin Geometry on the Stereochemistry of Lewis Acid Mediated Additions of Crotylstannanes to Aldehydes
    作者:Gary E. Keck、Kenneth A. Savin、Erik N. K. Cressman、Duane E. Abbott
    DOI:10.1021/jo00104a054
    日期:1994.12
    The role of the double bond geometry (E/Z stereochemistry) in reactions of crotylstannanes with aldehydes has been examined for representative ''simple'', alpha-alkoxy, and beta-alkoxy aldehydes. For the reaction of crotylstannane with simple achiral aliphatic, aromatic, or alpha,beta unsaturated aldehydes mediated by BF3.Et(2)O, use of the E crotylstannane gives much enhanced syn selectivity over that obtained with Z (e.g., 43:1 vs 4:1 with benzaldehyde). A synclinal transition state in which the CH(2)SnBu(3) group is gauche to oxygen is proposed to explain these results. For alpha-alkoxy aldehydes, use of the E stannane with MgBr2 gives the highest syn selectivity, while the Z stannane gives slightly better stereoselectivity with beta-alkoxy substrates. In contrast, the use of TiCl4 gives anti products preferentially from the E stannane and either alpha or beta-alkoxy substrates.
  • A total synthesis of (.+-.)-tirandamycin B
    作者:Stephen J. Shimshock、Robert E. Waltermire、Philip DeShong
    DOI:10.1021/ja00023a029
    日期:1991.11
    The total synthesis of the dienoyl tetramic acid antibiotic (+/-)-tirandamycin B is described. The key transformations of the strategy include (1) cyclization of pyranone 14 with fluorosilicic acid to provide the 2,6-dioxabicyclo[3.3.1]nonane system of the natural product, (2) reductive removal of the benzyl ether from enone 15, and (3) attachment of the tetramic acid moiety by using the Schlessinger phosphonate protocol. Protection of the primary hydroxyl function of tirandamycin B as the triisopropylsilyl (TIPS) ether was crucial to the success of the strategy.
