• Qualitative Analysis of the Stability of the Oxazine Ring of Various Benzoxazine and Pyridooxazine Derivatives with Proton Nuclear Magnetic Resonance Spectroscopy
  作者：Gerard P. Moloney、David J. Craik、Magdy N. Iskander

  日期：1992.7

  3-benzoxazine and 3,4-dihydro-1,3-pyridooxazine derivatives was synthesized, and the hydrolysis of the derivatives was studied with proton nuclear magnetic resonance spectroscopy. The oxazine derivatives underwent various degrees of hydrolysis when H2O was added to dimethyl sulfoxide solutions of the compounds. The rates and extents of decomposition of the oxazine ring systems depended on the electronic effects

  合成了一系列的3,4-二氢-1,3-苯并恶嗪和3,4-二氢-1,3-吡啶并恶嗪衍生物，并利用质子核磁共振波谱研究了这些衍生物的水解。当将H 2 O加入到化合物的二甲基亚砜溶液中时，恶嗪衍生物经历了不同程度的水解。恶嗪环系统分解的速率和程度取决于分子内取代基的电子效应。对恶嗪分解期间产生的质子核磁共振谱以及恶嗪衍生物的稳定性趋势的研究表明在水解机理中形成了中间体。

• Studies on the benzoxazine series. Part 3—Preparation and13C NMR structural Study of γ Effects of SomeN-substituted 3,4-dihydro-2H-1,3-benzoxazines
  作者：Kari Neuvonen、Kalevi Pihlaja

  DOI：10.1002/mrc.1260280309

  日期：1990.3

  Seventeen N-substituted 3,4-dihydro-2H-1,3-benzoxazines [N-substituent = Et, Pri, But, CH2C6H5 or CH(CH3)C6H5] were prepared and their structures studied in the light of 13C chemical shifts. The γ effects caused by C(α)-methyl or C(α)-phenyl substitution at the heterocyclic ring carbons were found to be valuable structural parameters. By using N-tert-butyl derivatives as models, and by dividing γtot effects into their components, the rotamer populations due to the rotation around the NC(α) bond could be evaluated. The method also allows the configurational assignment of diastereomeric N-α-methylbenzyl derivatives. The effect of the half-chair structure on the 13C NMR parameters is discussed.

  研究人员制备了 17 种 N 取代的 3,4-二氢-2H-1,3-苯并噁嗪[N 取代基 = Et、Pri、But、CH2C6H5 或 CH(CH3)C6H5]，并根据 13C 化学位移研究了它们的结构。研究发现，杂环碳原子上的 C(α)-甲基或 C(α)-苯基取代引起的 γ 效应是有价值的结构参数。通过使用 N-叔丁基衍生物作为模型，并将γtot 效应分成不同的部分，可以评估围绕 NC(α)键旋转所产生的旋转体群。该方法还可以对非对映的 N-α-甲基苄基衍生物进行构型分配。该方法还讨论了半椅结构对 13C NMR 参数的影响。
