Tomato fruit extract: an environmentally benign catalytic medium for the synthesis of isoxazoles derivatives

One-pot multicomponent reaction between aromatic aldehyde, hydroxylamine hydrochloride and ethyl acetoacetate/ methyl acetoacetate for the synthesis of isoxazoles derivatives by employing tomato fruit extract as a catalytic medium has been developed. Tomato fruit extract was found to be a favorable catalytic medium for the synthesis of titled compounds. Mild reaction condition, ease of separation, moderate to high yield of the product, and short reaction time makes this method more attractive over earlier reported methods for the synthesis of isoxazoles derivatives.
