Iron-catalyzed deoxygenation and 2-sulfonylation of quinoline N-oxides by sodium sulfinates towards 2-sulfonyl quinolines
2018
AbstractAn iron(III)-catalyzed protocol towards 2-sulfonyl quinolines from quinoline N-oxides and sodium sulfinates was herein illustrated. The general and direct option featured for high efficiency (up to 91% yields) and good functional compatibilities (27 examples) in the Fe(III)-catalysis. Moreover, free radical mechanism was proposed for the one-pot deoxygenation and sulfonylation reaction based on the results of the control reactions.
