An efficient and eco-friendly synthetic method
has been established for synthesis of 7-hydroxy-4-methyl
coumarin and its derivatives using tamarind juice as a
biocatalyst. The condensation reaction of Substituted
phenol with ethyl acetoacetate (EAA) successfully carried
out using tamarind juice as a green and efficient catalyst
at 90°C in aqueous condition. This green biocatalyst has
been utilised effectively for pechmann reaction with good
yield of product, easy workup and eco-friendly reaction
conditions.
