  Synthesis of 3,5-Isoxazolidinediones and 1H-2,3-Benzoxazine-1,4(3H)-diones from Aliphatic Oximes and Dicarboxylic Acid Chlorides

  摘要：

  The synthesis of the title compounds was carried out by reacting dicarboxylic acid chlorides with oximes in the presence of excess triethylamine. Disubstituted malonyl chlorides gave 2-alkenyl-4,4-dialkyl-3,5-isoxazolidinediones (8a-f) and 2,2;-ethylidene-bis[4,4-dialkyl-3,5-isoxazolidinedione]s (9a-f). Compounds 9 were formed from 8 and its N-unsubstituted 3,5-isoxazolidinedione decomposition product. Phthaloyl chlorides reacted with acetone oxime to yield 3-(1-methylethenyl)-1H-2,3-benzoxazine-1,4(3H)-diones (16a-e). Products 16 spontaneously decomposed to give N-unsubstituted 1H-2,3-benzoxazine-1,4(3H)-diones (17a-e) at rates that were dependent on temperature and solvent. Kinetic studies showed that two of the compounds decomposed by zero-order kinetics under neutral conditions. Butanedioyl chloride did not produce a cyclic product.

  增强BODIPY的荧光和单线态氧生成能力：用吸电子基团修饰内苯基单元

  摘要：

  在此，合成并表征了内消旋-R-羧基苯基取代的BODIPY化合物（R ＝ CH 3，COOH，NO 2，H和Br 4）。通过紫外可见吸收，稳态和时间分辨荧光方法以及激光闪光光解技术，在非极性和极性溶剂中测量了这些化合物的荧光，激发三重态和单线态氧的形成特性。这些BODIPY表现出非常不同的荧光量子产率和寿命值，以及极性溶剂中单线态氧的形成能力。相反，这些化合物显示出非常相似的光谱形状和位置，在非极性溶剂中发出亮绿色的荧光。邻位的介绍苯单元上的-COOH导致荧光量子产率增加20倍。在苯基上进一步引入吸电子NO 2或COOH使BODIPY染料具有更高的产生单线态氧的能力（最多增加5倍），并导致荧光量子产率和寿命值急剧下降。溶剂极性的增加增强了单线态氧的产生和分子内荧光猝灭。分子内光诱导的电子/电荷从BODIPY核转移到羧苯基部分的存在解释了这一结果。

• [3 + 2] Cycloadditions of Azides with Arynes via Photolysis of Phthaloyl Peroxide Derivatives
  作者：Denghu Chang、Dan Zhu、Lei Shi

  日期：2015.6.5

  Photolysis of phthaloyl peroxides yields arynes, which undergo [3 + 2] cycloadditions with azides. This reaction tolerates a variety of organic azides and phthaloyl peroxides and affords the corresponding benzotriazoles in moderate to good yields at room temperature.
