  Thiosemicarbazones as Aedes aegypti larvicidal

  摘要：

  A set of aryl- and phenoxymethyl-(thio)semicarbazones were synthetized, characterized and biologically evaluated against the larvae of Aedes aegypti (A. aegypti), the vector responsible for diseases like Dengue and Yellow fever. (Q)SAR studies were useful for predicting the activities of the compounds not included to create the QSAR model as well as to predict the features of a new compound with improved activity. Docking studies corroborated experimental evidence of AeSCP-2 as a potential target able to explain the larvicidal properties of its compounds. The trend observed between the in silica Docking scores and the in vitro pLC50 (equals -log LC50, at molar concentration) data indicated that the highest larvicidal compounds, or the compounds with the highest values for pLC50, are usually those with the higher docking scores (i.e., greater in silica affinity for the AeSCP-2 target). Determination of cytotoxicity for these compounds in mammal cells demonstrated that the top larvicide compounds are non-toxic. (C) 2015 Elsevier Masson SAS. All rights reserved.

  complicated metabolism of 18a provided further insights for the design of newer related derivatives. The observation that the metabolic oxidation on the lateral chain's sulfur of 18a to sulfoxide maintained the antitussive properties suggested the introduction of isosteric functional groups with respect to the sulfoxide moiety. Subsequent structural modifications showed that hydrolyzable malonic residues

  An improved two-step synthetic route to allylic alcohols from aldehydes has been developed. A modification of the HWE reaction in H2O–2-PrOH (1 ∶ 1) and a convenient protocol to prepare AlH3 in THF from LiAlH4 and n-BuBr are the key factors in the improvement.

  copper-catalyzed C–O cross-coupling reaction between aryl bromides and aliphatic diols has been developed employing a cheaper, more efficient, and easily removable copper(II) catalyst. A broad range of aryl bromides were coupled with aliphatic diols of different lengths using 5 mol% CuCl2 and 3 equivalents of K2CO3 in the absence of any other ligands or solvents to afford the corresponding hydroxyalkyl aryl ethers

• The Synthesis of 5-Hydroxy-3-methylnaphtho[2,3-c]furan-4,9-dione and 5,8-Dihydroxy-1-methylnaphtho[2,3-c]furan-4,9-dione
  作者：Matthew J. Piggott、Dieter Wege

  DOI：10.1071/ch02253

  日期：——

  5-Hydroxy-3-methylnaphtho[2,3-c]furan-4,9-dione (1), a metabolite isolated from Aloe ferox and Bulbine capitata, has been synthesized by a sequence involving an annulation reaction between the anion of 4-methoxy-3-oxo-1,3-dihydroisobenzofuran-1-carbonitrile (8) and (E)-pent-3-en-2-one, followed by subsequent construction of the furan ring through allylic bromination, hydrolysis, and dehydration as the key steps. The formation of several unusual products observed in annulation reactions between (8) and O-protected derivatives of (E)-5-hydroxypent-3-en-2-one (9) can be rationalized by invoking the intermediacy of a reactive o-quinone methide. 5,8-Dihydroxy-1-methylnaphtho[2,3-c]furan-4,9-dione (2), another naturally occurring naphtho[2,3-c]furan-4,9-dione, has been prepared by a Friedel–Crafts acylation of 1,4-dimethoxybenzene with 2-methylfuran-3,4-dicarbonyl dichloride. Arguments are presented that 5,8-dihydroxynaphtho[2,3-c]furan-4,9-dione is a better structural representation than the alternative 4,9-dihydroxynaphtho[2,3-c]furan-5,8-dione tautomer in such systems, as the latter would contain a reactive isobenzofuran moiety.

  5- 羟基-3-甲基萘并[2,3-c]呋喃-4,9-二酮（1）是从 Aloe ferox 和 Bulbine capitata 中分离出来的一种代谢物，其合成过程包括 4-甲氧基-3-氧代-1、3-二氢异苯并呋喃-1-甲腈 (8) 与 (E)-pent-3-en-2-one 之间的环化反应，然后通过烯丙基溴化、水解和脱水等关键步骤构建呋喃环。在(8)和(E)-5-羟基戊-3-烯-2-酮的 O 保护衍生物(9)之间的环化反应中观察到的几种不寻常产物的形成，可以通过引证反应性邻醌甲酰胺的中间产物而得到合理解释。5,8-二羟基-1-甲基萘并[2,3-c]呋喃-4,9-二酮（2）是另一种天然存在的萘并[2,3-c]呋喃-4,9-二酮，是通过 1,4 二甲基苯与 2-甲基呋喃-3,4-二羰基二氯化物的弗里德尔-卡夫酰化反应制备的。有观点认为，在这种体系中，5,8-二羟基萘并[2,3-c]呋喃-4,9-二酮比 4,9-二羟基萘并[2,3-c]呋喃-5,8-二酮同系物的结构更好，因为后者含有活性异苯并呋喃分子。
