  • ISSN : 0379-4350



A rapid and green procedure has been introduced for the preparation of tetrahydrochromeno[4,3-]chromene-6,8-dione derivatives in the presence of magnesium perchlorate. This solvent-free procedure offers some advantages such as short reaction times, high yields, an easy-to-handle catalyst, and avoidance of organic solvents. In this work four new compounds are reported.
