New synthetic strategy for Friedlander condensation of 4‐amino‐2‐oxo‐2H‐chromene‐3‐carbaldehyde by heterogeneous catalysis

Chromenopyridines are an important class of compound because of their diverse biological activities. In the present work, we have developed convenient route for the synthesis of chromeno[4,3‐b] pyridine derivatives (3a–e, 5a–e, and 7a–d) by Friedlander condensation of 4‐amino‐2‐oxo‐2H‐chromene‐3‐car...
