摘要：
A simple and efficient metal-free methodology is presented to access fluorescent beta-carboline tethered pyrido(2,3-c)carbazole derivatives (Nitramarine analogues) via A(3)-coupling of 1-formyl-9H-beta-carbolines, 3-amino-9-ethylcarbazole, and terminal alkynes. The advantages of this approach are operationally simple procedure, use of non-toxic and inexpensive catalyst (I-2), broad substrate scope, and good yields of products. Moreover, these products showed excellent luminescent properties with quantum yield (Phi(F)) up to 60%. (C) 2020 Elsevier Ltd. All rights reserved.
