Synthesis of pyrano and furanoquinolines using silica chloride or amberlyst-15 as a heterogeneous catalyst

Biswanath Das; Majjigapu Ravinder Reddy; Harish Holla; R. Ramu; Katta Venkateswarlu; Yerra Koteswara Rao

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.
