The SNAr reaction of 2-chloroazulene derivative 1 with ethoxycarbonyl groups at the 1,3-positions of the azulene ring with several amines afforded the corresponding 2-aminoazulenes 3–9 in excellent yields. 2-Chloroazulene (2) without the electron-withdrawing groups reacted with highly nucleophilic cyclic ami

2019年11月1日 · Without any catalysis, 2-amino-azulene can easily react with Br 2 to prepare 2,6-substituted azulene. Further reactions can lead to much useful 2,6-substituted azulene, which can be applied into organic solar cells (OSCs), organic field-effect transistors (OFETs), and more [32].

The synthesis of the key building blocks 2-aminoazulene (24), 2-amino-6-bromoazulene (26), and its corresponding carbamate, tert-butyl N-(6-bromoazulen-2-yl)carbamate (27), used in their synthesis is presented in Scheme 7A.

2024年3月22日 · The reaction of azulen-2-amine with oxalyl dichloride provided azuleno [2,1-b]pyrrole-2,3-dione, 40.2, which after condensation with isatoic anhydrides, 40.3, afforded azuleno [1′,2′:4,5]pyrrolo [2,1-b]quinazoline-6,14-dione, 40.4, in high yield .

The reaction of 2H-cyclohepta[b]furan-2-ones with active methylenes provides 2-amino- and 2-hydroxyazulene derivatives, similar to the azulene synthesis from tropone derivatives

2-Amino-(1-(2-nitrophenylsulfinyl)azulene derivatives were synthesized by the reaction of 2-aminoazulene with 2-nitrobenzenesulfonyl chloride. Crystal structures of these compounds were determined by X-ray diffraction analysis.

The result of the application of this method to the crystal of 2-amino azulene ( a =11.62, b =10.76, c =6.32 Å, Z =4, space group P b n 2 1 ) was given.

Synthesis of 2-amino- and 2-arylazoazulenes via nucleophilic aromatic substitution of 2-chloroazulenes with amines and arylhydrazines. The SNAr reaction of 2-chloroazulene derivative 1 with ethoxycarbonyl groups at the 1,3-positions of the azulene ring with several amines afforded the corresponding 2-aminoazulenes 3-9 in excellent…
