We report the synthesis of flavin-stoppered hydrogen bonded [2] rotaxanes 1 and 2. We also report the electrochemically controllable properties of these systems in solution, and for derivative 2, as an electropolymerized thin film.
通过哌啶催化的2-氨基苯并咪唑,芳香族醛和1,3-二酮在异丙醇水溶液中的三组分反应实现苯并咪唑并[2,1 - b ]喹唑啉-1(1 H)-的超声辅助合成。在我们确定了一锅反应中不寻常的反应中间体之后,首先怀疑了这种机制。前所未有的偶联反应,它涉及2-氨基苯并咪唑对原位生成的迈克尔加合物的亲核攻击,然后发生电环形成反应。与普遍接受的机理相反,2-氨基苯并咪唑与Knoevenagel加合物的直接反应不能释放目标化合物。

A fused heterocyclic compound of formula (1): wherein, A1 and A2 represent a nitrogen atom or the like, R1, R2, R3 and R4 represent a halogen atom or the like, R2 and R3 represent a halogen atom or the like, R5 represents a C1-C6 chain hydrocarbon group optionally substituted with one or more halogen atoms, or the like, R6 and R7 represent a C1-C4 chain hydrocarbon group substituted with one or more halogen atoms, or the like, and n represents 0 or 1, has an excellent noxious arthropod controlling effect.
and eco-friendly method for the synthesis of o-nitroarylamine from o-nitroaryl sulfonic acid via ipso nucleophilic aryl substitution by amine is described. The products have been obtained with good yields at room temperature without the assistance of any metal, activating agent, or toxic oxidant. This method is useful for racemization-free synthesis of N-aryl amino acid esters.
