The Highly Efficient Synthesis of 2-Arylene-Indene-1,3-Dione Derivatives in Gluconic Acid Aqueous Solution
Six kinds of 2-arylideneindan-1,3-diones derivatives are sythesized by the Knoevenagel condensation of indan-1,3-dione with aromatic aldehydes in gluconic acid aqueous solution(GAAS).The reaction has the advantages of mild conditions,simple operation,high yields(84％to 95％),GAAS reused for several times.
