The present invention relates to (E)-ethyl 2-(2-methyl-3-((2-(naphtho[2,1-b]furan-2-carbonyl)hydrazono)methyl)-1H-indol-1-yl)acetate as a novel tubulin polymerization inhibitor and a method for synthesizing the same. The compound of the present invention can inhibit mitosis and induce apoptosis and thus be used as an anticancer agent, by binding to tubulin to inhibit microtube polymerization. According to the synthesis method of the present invention, the reaction is simplified and the efficiency is 60%, or higher, leading to a very high yield, thereby providing an effective synthesis method.

chemistry, and efficient methods for their synthesis are in high demand. This applies in particular to atropisomers derived from five-membered aromatic rings because their lower barrier for rotation among the biaryl axis limits their asymmetric synthesis. We report here an enantioselective C–H functionalization method using our chiral RhJasCp complex for the synthesis of the biaryl atropisomer types that
轴向手性阻转异构化合物广泛用于不对称催化和药物化学中,对合成的有效方法有很高的要求。这尤其适用于衍生自五元芳族环的阻转异构体,因为它们在联芳基轴之间旋转的较低阻挡层限制了它们的不对称合成。我们在这里报告了一种手性Rh Jas Cp络合物的对映选择性CH功能化方法,用于合成可从三个不同的五元环杂环中获得的联芳基阻转异构体类型。

A modular tandem synthesis of 2-carboxybenzofurans from 2-gem-dibromovinylphenols has been established based on a sequence of Cu-catalyzed intramolecular C–O coupling and Mo(CO)6-mediated intermolecular carbonylationreactions. This protocol allowed one-step access to a broad variety of functionalized benzofuran-2-carboxylic acids, esters, and amides in good to excellent yields under Pd- and CO gas-free
