Abstract
The coupling of three components, anilines, benzaldehydes and 3,4-dihydro-2H- pyran or 2,3-dihydrofuran to prepare the corresponding pyrano or furanoquinolines has been achieved efficiently using silica chloride or Amberlyst-15 as a heterogeneous catalyst. Amberlyst-15 can be recovered and reused.
