    Formal Synthesis of Merrilactone A Using a Domino Cyanide 1,4-Addition–Aldol Cyclization
    摘要:
    A formal synthesis of merrilactone A has been completed using a domino 1,4-addition-aldol process as the key step. Both iodo- and cyano-1, 4-addition-aldol cyclizations were productive in forming the highly hindered C1-C9 bond linking vic-quaternary and tertiary stereocenters. The latter method was used to complete a formal total synthesis of the natural product.

  • Synthesis of Hetero Atom Modified Pyrromethenones
    作者:Christian Bongards、Wolfgang Gärtner
    DOI:10.1002/ejoc.200700656
    日期:2007.12
    six heteroaromatic compounds, ethyl-/methyl- and dimethylfuranones, thiophenones, and cyclopentenones, was synthesized and condensed with a methyl methylpropionate substituted pyrrole, yielding the “right” half of open-chain tetrapyrroles. These compounds serve as light-inducible chromophores in the plant photoreceptor phytochrome. Three-dimensional structure analysis of the 10-oxapyrromethen-1-one
    合成了一系列六种杂芳族化合物,乙基-/甲基-和二甲基呋喃酮、噻吩酮和环戊烯酮,并与甲基丙酸甲酯取代的吡咯缩合,产生开链四吡咯的“右”半部分。这些化合物用作植物光感受器光敏色素中的光诱导生色团。10-oxapyrromethen-1-one 25 的三维结构分析揭示了平面构象,类似于二吡咯甲酮母体化合物,由吡咯质子和呋喃酮氧原子之间形成的氢键稳定。所有六种吡咯取代的杂芳族衍生物 25-30 在可见光谱中都显示出吸光度,具有高摩尔消光系数。(© Wiley-VCH Verlag GmbH & Co. KGaA,69451 Weinheim,德国,2007)
