    Stereoselective 1,2-Additions of α-Alkoxymethyllithiums to Aldehydes
    摘要:
    [GRAPHICS]A chiral derivative of tributylstannylmethanol, readily prepared from L-valine, undergoes Sn-Li exchange to provide an alpha -alkoxyorganolithium that adds to aldehydes with up to 91:9 dr. The diastereoselectivity depends on the solvent and alkyllithium used for transmetalation. Treatment of adducts with acid allowed recovery of the chiral auxiliary and diol with complete stereochemical integrity.

  • C-Glycosides to Fused Polycyclic Ethers. A Formal Synthesis of (±)-Hemibrevetoxin B
    作者:Jon D. Rainier、Shawn P. Allwein、Jason M. Cox
    DOI:10.1021/jo001514j
    日期:2001.2.1
    This paper describes a formal total synthesis of the marine ladder toxin hemibrevetoxin B from Danishefsky's dienes. This approach couples the generation of C-glycosides from cyclic enol ethers with metathesis or acid-mediated annulation reactions. The result is a highly efficient synthesis of the tetracyclic ring system of hemibrevetoxin B.

    enantiomer of batzelladine B methanolysis product 10 in 10 steps and 25% overall yield from 2-nonanone and methyl acetoacetate. The asymmetric synthesis of 10 establishes that the absolute configuration of the tricyclic portion of batzelladine B (2) is 25aR,28S,30R. The 4-methyl-7-alkyl-1,2,2a,3,4,5,6,7,8,8a-decahydro-5,6,8b-triazaacenaphthalene-3-carboxylic acid subunit, e.g., 29, of batzelladine alkaloids

    A 4‐substituted‐1‐tosyl‐1,2,3‐triazole‐based stereoselective synthesis of structurally diverse oxaspirocycles is reported. The synthesis involves Rh‐catalyzed loss of nitrogen from 4‐substituted‐1‐tosyl‐1,2,3‐triazoles, Grignard reaction, and a ring‐closing metathesis reaction as key steps. By employing readily available and stable 4‐substituted‐1‐tosyl‐1,2,3‐triazoles as surrogates of diazo compounds
    据报道,基于4-取代-1,对甲苯基1,2,3-三唑的立体选择性合成结构多样的oxaspirocycles。合成涉及关键步骤,其中包括Rh催化的4-取代-1-甲苯磺酰基1,2,3-三唑的氮损失,格氏反应和闭环易位反应。通过使用现成的,稳定的4-取代-1-甲苯磺酰基1,2,3-三唑作为重氮化合物和氮源的替代物,获得了两种类型的氧杂螺环。后者含有相邻的氮立体中心,可以作为许多天然产物的核心结构。该化学方法已成功应用于(±)-溴代螺螺啉和(±)-stemona-lactam R的全部合成中。

    Important precursors (1 and 2) for the synthesis of 4-substituted indole derivatives were readily obtained by acid treatment of a tosylamide (13), which was prepared in a single operation by treatment of 10 with N-tosyl-N', N'-dimethylformamidine (TsN=CHNMe2). Compound (10) was effectively synthesezed from nitromethane and acrolein by way of a nitro compound (15). A novel indole formation reaction from the tosyl-amide (13) to gain short access to 4-alkoxyindoles, such as 16, 17, 19, and 21 is presented.
