One-pot sequential synthesis of 3-carbonyl-4-arylbenzo[f]indole and 3-carbonyl-4-arylnaphthofuran fluorophores
The development of novel methods for the construction of valuable fluorophores, 3-carbonyl-4-arylbenzo[f] indoles and 3-carbonyl-4-arylnaphthofurans, is described. In this protocol, the important polycarbonyl key intermediate was generated via the ketonization of ortho-alkynylarylketone tethered with a 1,3-dicarbonyl moiety. This intermediate reacted with an amine to selectively form a pyrrole intermediate, followed by cyclization in acetic acid to provide 3-carbonyl-4-arylbenzo[f] indole. Importantly, these conditions did not cause any epimerization of the stereogenic center in chiral amine substrates. Moreover, the polycarbonyl intermediate could also be utilized to prepare 3-carbonyl-4-arylnaphthofuran using In (OTf) 3 as a catalyst for double cyclization under thermal conditions. In addition, the fluorescence properties of both fluorophores were also studied.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 574-98-1. HPLC of Formula: C10H8BrNO2.
