Abstract:

By using o-aminophenyl methanol as the starting material and undergoing a dehydrogenation reaction, [RuCl2(p-cymene)]2/AgOTf was finally employed as the co-catalyst system upon a systematical screening of catalysts, which enables the dehydrogenation of o-aminophenyl methanol to undergo a cross-coupling reaction with terminal aryl alkynes, affording a series of 2-aryl quinolines in 39% to 47% yields. The study has demonstrated a new method for the synthesis of quinolines from o-aminophenyl methanol and terminal aryl alkynes, which is an important complement to the synthesis of quinoline derivatives.
