关于我们一般合成多环杂芳族化合物的机理方面的研究表明,遵循方案2中概述的反应序列。在我们的合成条件下,邻位重排(8)→(9)优于已知在酸性条件下发生的对位重排。在分子间反应中,苯胺曼尼希碱(29)被转化为苯并[ a ] r啶(30)。合成似乎仅限于推定的中间体(9)不属于酰胺基团的底物。在这些研究过程中,已经发现了三环化合物(24)和(25)的有效合成。

naphthalene rings is a critical feature of the chelation process. The formation of [Co(R-az)3] from [Co(R-az)2] and from [Co(R-Haz)2X2] in the presence of air occurs easily and is acid catalysed. [Co(R-sb)3] is formed only under vigorously oxidising conditions. The isoelectronic ligands R-Haz and R-Hsb should not be regarded as identical in their reactivity towards cobalt(II).

of a novel class of platinumcomplexescontaining Schiff bases as O,N-bidentate ligands is described as are the solution and solid state properties of the uncomplexed ligands. The platinumcomplexes were prepared from [PtBr2(COD)] (COD = 1,5-cyclooctadiene) and N-(2-hydroxy-1-naphthalidene)anilinederivatives in the presence of base (NaOBut). Instead of a substitutionreaction to afford cationic species

ethanol. Ruthenium(III) complexes of the type [Ru(Ln)2(H2O)2]Cl have been synthesized by the reaction of RuCl3·nH2O with the Schiff base ligands (in a molar ratio 1:2) in ethanol. The ligands and their Ru(III) complexes have been characterized by elemental analysis, magnetic susceptibility, spectroscopic (FTIR, UV–vis, 1H NMR and X-ray diffraction) and thermal analysis techniques. All the ruthenium(III)
we designed and synthesized 50 N-benzylideneaniline compounds with the help of CADD. And subsequent in vitro studies leading to the optimized compound SMU-A0B13 with most potent inhibitory activity to TLR2 (IC50=18.21 ± 0.87 μM). Preliminary mechanism studies indicated that this TLR2 inhibitor can work through the NF-κB signaling pathway with high specificity and low toxicity, and can also efficiently
