  Effects of electron-withdrawing substituents on DPPH radical scavenging reactions of protocatechuic acid and its analogues in alcoholic solvents

  摘要：

  The DPPH (2,2-diphenyl-l-picrylhydrazyl) radical scavenging activity of protocatechuic acid (3,4-dihydroxybenzoic acid) and its related catechols was examined. Compounds possessing strong electron-withdrawing substituents showed high activity. NMR analysis of the reaction mixtures of catechols and DPPH radical in methanol showed the formation of methanol adducts. The results suggest that high radical scavenging activity of catechols in alcohol is due to a nucleophilic addition of an alcohol molecule on o-quinones, which leads to a regeneration of a catechol structure. Furthermore, the radical scavenging activity in alcohols would largely depend on the electron-withdrawing/donating substituents, Since they affect the susceptibility toward nucleophilic attacks on o-quinone.

  阿尔特努伊醇结构与全合成的修订

  摘要：

  描述了所报道的阿替尼醇结构的全合成。合成化合物和天然产物的 1H NMR 谱的比较表明最初提出的结构不正确。因此，合成了两种结构异构体。其中一种化合物的光谱——一种最初被提议为交替烯醇结构的结构——与天然产物的光谱完美匹配。因此，以间苯二酚和原儿茶醛为起始原料，以 10 步和 23% 的产率实现了阿替尼醇的全合成，其中最长的线性序列由 6 步组成。关键步骤是伴随内酯环形成的 Suzuki 偶联。交替性与交替性是否相同尚不能确定。

  A novel palladium‐acid co‐catalyzed C(sp)−C(sp2) cleavage of alkynoates for the construction of dibenzo[c,h]xanthene derivatives is reported. A catalytic amount of triflic acid (TfOH) afforded an efficient transformation into the final product. Furthermore, a reduction process of alkynoates was observed during the formation of dibenzo[c,h]xanthene, preliminary mechanistic studies indicated that the

  For the sake of establishment of a versatile synthetic method for benzo [c] phenanthridine alkaloids, improvement of the Robinson synthetic method was examined. Thirteen chalcones (7a-m) were prepared by condensation of two acetophenone derivatives (15 and 16) with eleven benzaldehyde derivatives (19a-k) as fundamental starting materials. Hydrocyanation of these chalcones (7a-l) except one (7m) gave the corresponding 2, 4-bisaryl-4-oxobutyronitriles (8a-l). Eleven 2, 4-bisaryl-4-oxobutyramides (9a-k) were also prepared.

  为了建立一种通用的苯并[c]菲啶生物碱合成方法，对Robinson合成方法进行了改进。通过将两个乙酰苯衍生物（15和16）与十一种苯甲醛衍生物（19a-k）缩合，制备了十三种查尔酮（7a-m）作为基本起始材料。除了一个查尔酮（7m）外，这些查尔酮（7a-l）的氰化反应得到了相应的2,4-双芳基-4-氧代丁腈（8a-l）。还制备了十一种2,4-双芳基-4-氧代丁酰胺（9a-k）。

  A concise 7-step total synthesis of (±)-fumimycin in 11.6% overall yield is reported. An acid-catalyzed intramolecular aza-Friedel–Crafts cyclization was developed to construct the benzofuranone skeleton of the natural product bearing an α,α-disubstituted amino acid moiety in a single step. Regioselective chlorination followed by a Suzuki–Miyaura cross-coupling rapidly enabled the preparation of a

  Various catechol derivatives (β-substitued 3, 4-dihydroxystyrenes, 1-substituted 3, 4-dihydroxybenzenes, and 6-substituted 2, 3-dihydroxynaphthalenes) were synthesized and their inhibition of 5-lipoxygenease was assayed. Their structure-activity relationships were examined quantitatively with substituent and structural parameters and regression analysis. The variations in the inhibitory activity were explained in bilinear hydrophobic parameter (log P) terms, and steric (molecular thickness) and electronic (proton nuclear magnetic resonance (1H-NMR) chemical shift of the proton adjacent to the catechol group) parameter terms. The hydrophobicity of the inhibitor molecule was important, and the optimum valur of log P was about 4.3-4.6, beyond which inhibition did not increase further. A lower electron density of the aromatic ring containing the catechol group and the greater thickness of the lipophilic side chains were unfavorable to the activity. The results added a physicochemical basis for the selection of candidate compounds for developmental studies.

  合成了多种儿茶酚衍生物（β-取代的3,4-二羟基苯乙烯、1-取代的3,4-二羟基苯和6-取代的2,3-二羟基萘），并测试了它们对5-脂氧合酶的抑制作用。通过取代基和结构参数进行定量结构-活性关系研究，并采用回归分析。抑制活性的变化可以用双线性疏水参数（log P）、空间（分子厚度）和电子（邻近儿茶酚基团的质子的核磁共振氢谱化学位移）参数来解释。抑制剂分子的疏水性很重要，log P的最佳值约为4.3-4.6，超过此值抑制作用不再增加。含有儿茶酚基团的芳环电子密度较低以及亲脂性侧链厚度较大均不利于活性。这些结果为候选化合物的发展研究提供了物理化学基础。
