“…As well as naphthalene substrates, Nagarajan and Meesala reported the oxidative coupling of aminocarbazoles 33 and aminoindoles by using ac opper oxidant (Scheme 19). [51] They investigated the effective production of the corresponding pyrazine-fused dimers 34 with copper salts under air.T hey proposed am echanism involving the transformation of hydrazocarbazole by [3,3]-sigmatropicr earrangement followed by benzidine rearrangement, leading to formation of the phenazine product exclusively.…”

In this review,w ef ocus on the synthesiso fp-conjugated functional molecules by the oxidation of aromatic amines, which is one of the most effective methods fort he constructiono fC ÀC, CÀN, and NÀNb onds between two pconjugated molecular units,a nd consider their characteristics and applications. Polyanilines are the most common products of the oxidation of aromatic amines;h owever,a zobenzenes, phenazines, and 1,1'-binaphthyl-2,2'-diaminesm ay be produced in this manner also, depending on the reaction conditions. Recent advances in the methodology of aniline oxidation have led to the development of high-regioselectivity industrial-scale syntheses of optically or electroactive pfunctional dyes containing nitrogen atoms. In particular,t he regioselective fusion of p-extended aromatic amines can be used to prepare distorted p-conjugated molecules under mild reactionc onditions, allowing the construction of unprecedented curved nitrogen-containing p-conjugated molecules.Scheme1.Aniline oxidations.Scheme2.Reactionpathways for aniline oxidation.[a] Prof.

“…In 2014, Meesala et al 31 have developed a simple and an efficient method to synthesize a new series of ellipticine analogues using the Vilsmeier-Haack reagent (Scheme 1). They described the synthesis of pyrido [3,2-b]carbazoles and pyrido [2,3-c]carbazoles by treating N-(carbazol-3-yl)acetamides 1a-e with DMF (2.5 equiv) and POCl 3 (10.0 equiv) at 70 °C for 12 hours.…”
