A simple method for the synthesis of novel chromene-indanedione derivatives(3) has been developed by the reaction of 2-hydroxychalcones(1) with 1,3-indanedione(2) in reflux toluene under catalyst-free conditions. All the compounds were characterized by means of 1H NMR, 13 C NMR, IR and HRMS. This reaction probably underwent a domino Michael addition/cyclization/oxidation process. The UV-Vis spectroscopy indicated that the maximum absorption wavelengths of the products 3a~3h were at the range of 464~482 nm.
