  氰化物是通过好氧氧化轻松合成苯并稠合杂芳族化合物的有力催化剂

  摘要：

  已经开发了通过氰化物阴离子催化的需氧氧化高效合成苯并稠合杂芳族化合物的方法。衍生自2-氨基苯酚和醛的席夫碱在敞口烧瓶中，在环境条件下，不使用任何外部金属助氧化剂和碱的情况下，在催化量氰化物的存在下，以高收率提供了相应的苯并恶唑。此外，我们已经开发了一种催化顺序一步法，用于合成苯并恶唑，方法是将催化量的NaCN添加到由2-氨基苯酚和醛原位生成的席夫碱中，而无需分离亚胺中间体。该一锅法方案进一步扩展为由2-氨基硫酚和醛合成苯并噻唑。

  synthesis of 2-substituted benzoxazoles from Schiff bases via aerobic oxidation has been developed. The products from various Schiff bases were obtained in high yields in an open flask under ambient conditions without other external oxidants. We have also developed a simple one-step protocol for the synthesis of benzoxazoles from aminophenol and the corresponding aldehydes in the presence of cyanide without

  We herein report an unprecedented addition reaction of pinacol gem-difluoroallylborates and imines enabled by a neighboring phenolic group in an N-protecting group under catalyst-free conditions, thus facilitating the construction of a wide range of racemic gem-difluorohomoallylamine derivatives. Based on the control experiments, a plausible transition state via the Zimmerman–Traxler model was proposed

  作者：B. F. Mirjalili、A. Bamoniri、E. Bagheri

  DOI：10.1007/s13738-015-0795-5

  日期：2016.5

  1,3-Benzoxazoles via oxidative cyclization of corresponding o-hydroxyarylidene anilines was synthesized in the presence of KMnO4/HOAc system. This system also was applied for the one-pot synthesis of 1,3-benzoxazoles from o-amino phenols and aldehydes. The both protocols were processed at room temperature under solvent-free conditions with good to excellent yields.

  日期：2019.5

  A novel series of amide 1,3,4-oxadiazole linked benzoxazole derivatives 12a-12j are synthesized and their anticancer activity is screened against four human cancer cell lines including A549 (Lung cancer), MCF7 (Breast cancer), A375 (Melanoma cancer), HT-29 (Colon cancer) using Combretastatin-A4 as a control drug. Among the synthesized compounds, 12c and 12g demonstrate potent anticancer activity against HT-29 cancer cell line with IC50 values of 0.018 and 0.093 mu M, respectively, which is higher than the standard drug.
• A closer look at the formation of bicyclometalated and cyclometalated ruthenium carbonyl complexes

  To study steric and electronic factors that affect the C-H activation of Schiff bases by the complex [Ru(PPh3)(2)(CO)(2)Cl-2], systematic spectroscopic analyses were performed for a family of Ru(II) complexes of type [Ru(PPh3)(2)(CO)L]. Among eight Schiff bases [H(2)Ln (n = 1-8)], synthesized by condensation of methyl-4-formyl benzoate with 4-aminoacetophenone, 1-naphthylamine, 2-amino-5-chloropyridine, 8-aminoquinoline, semicarbazide hydrochloride, 2-aminophenol, thiosemicarbazide and 2-aminothiophenol, it was observed that the C-H activation was dependent on the kind as well as the position of the coordinating atoms. The C-H activation of the Schiff bases was most facile in the formation of a Ru-CNO configuration followed by Ru-CNS, Ru-CNN, and Ru-CNC configurations, whereas for a Ru-NC(methine) configuration the activation was the slowest. X-ray crystal structures for five cycloruthenated complexes are reported. Detailed electrochemical studies reveals the redox behavior of the complexes and DFT calculations were performed to obtain geometry optimized structure of all other complexes and to get an insight of the electronic spectral behavior.
