FeCl<sub>3</sub>-promoted tandem 1,4-conjugate addition/6-<i>endo-dig</i> cyclization/oxidation of propargylamines and benzoylacetonitriles/malononitriles: direct access to functionalized 2-aryl-4<i>H</i>-chromenes
An efficient and concise procedure has been developed for the synthesis of functionalized 2-aryl-4H-chromenes based on a tandemreaction of propargylamines and benzoylacetonitriles/malononitriles in the presence of FeCl3 as an environmentally friendly promoter. This reaction involves a highlyefficienttandem sequence consisting of 1,4-conjugate addition, 6-endo-dig cyclization, and oxidation. This
