  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）

  In one aspect of the present invention, a UV-protective coating composition is described. The UV protective coating composition includes an acrylate polymer; and a non-crystallizing UV-absorber composition. The non-crystallizing UV absorber composition includes a dibenzoylresorcinol and at least one triazine compound. The dibenzoylresorcinol is present at a level in the range of from about 10 weight percent to about 25 weight percent, based on the total weight of the coating composition. Also provided is an article that includes the UV protective coating composition, and a method to protect the article.

• Formal Synthesis of Merrilactone A Using a Domino Cyanide 1,4-Addition–Aldol Cyclization
  作者：Naim Nazef、Robert D. M. Davies、Michael F. Greaney

  DOI：10.1021/ol301513h

  日期：2012.7.20

  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.
