Direct synthesis of polysubstituted quinoline derivatives by InBr3-promoted dimerization of 2-ethynylaniline derivatives.
InBr3 promotes the dimerization of 2-ethynylaniline derivatives containing an unsubstituted terminal carbon leading to the production of polysubstituted quinoline derivatives in good yield.
