Abstract:

In this work, an efficient method for the synthesis of 3-carboxycoumarins was reported via Knoevenagel condensation. The reaction of Meldrum’s acid with substituted salicylaldehyde in the presence of polymeric magnetic nanocatalyst. This protocol has many advantages such as short reaction time, high yield, and easy isolation of the synthesized catalyst.

Keywords: Nanocatalyst, green chemistry, coumarin, salicylaldehyde, Knoevenagel condensation.
