Treatment of 3-aryl-2-propyn-1-ols with diaryliodonium salts, followed by the reaction with NIS and BF3 gave 4-aryl-3-iodochromenes, treatment of N-tosyl 3-aryl-2-propynyl-1-amines with diaryliodonium salts, followed by the reaction with NIS and BF3 gave 4-aryl-3-iodoquinolines, and treatment of 3-aryl-2-propynoic acids with diaryliodonium salts, followed by the reaction with TBAB and Na2S2O8 gave 4-aryl-3-bromocoumarins in good yields, respectively. Those preparation methods are one-pot reactions of chromene, quinoline, and coumarin units. Moreover, those obtained 4-aryl-3-iodochromenes, 4-aryl-3-iodoquinolines, and 4-aryl-3-bromocoumarins were transformed to various 4-arylcoumarine derivatives and 4-arylquinoline derivatives by their oxidation, reduction, and coupling reaction with Pd complex.
