One pot synthesis of acid esters by Stobbe condensation of alkylidene / arylidene succinates and aldehydes or ketones, their subsequent hydrolysis to diacids hasreported. TheStobbe condensation of various aromatic aldehydes or ketones with dimethyl succinate gives different types of cyclized productsthrough green approach. The improved yields of Fulgenic acid and its anhydridehave observed by the green approach method as compared with other classical methods employed so far.The antioxidant activity of anhydride compounds have done by using DPPH.
Green synthesis, Hexamethylenetetramine, Stobbe condensation, aryl aldehydes& ketones and their products.
