Straightforward Bienaymé and copper catalyzed N-arylation sequence to access diverse 5H-pyrido[2′,1′:2,3]imidazo[4,5-b]indoles and analogues
摘要:
A two-step sequence is reported giving access to diverse 5H-pyrido[2',1':2,3]imidazo[4,5-b]indoles and analogues via a Bienayme multicomponent reaction followed by N-arylation. The desired polycylic scaffolds were obtained in high yield using copper iodide in association with TMEDA in aqueous or dioxane media. (C) 2012 Elsevier Ltd. All rights reserved.
