An efficient one-pot synthesis of pyrano- and furoquinolines employing two reusable solid acids as heterogeneous catalysts
Srinivas,Das, Biswanath
, p. 1715 - 1718 (2004)
Two solid acids, Fe3+-K-10 montmorillonite clay and HY-zeolite have been employed efficiently for single-step synthesis of pyrano- or furoquinolines in high yields and high diastereoselectivities by coupling of three components: anilines, benzaldehydes and 3,4-dihydro-2h-pyran or 2,3-dihydrofuran. Both the heterogeneous catalysts are recoverable and recyclable.
