An environment friendly synthesis of 1,8-dioxooctahydroxanthenes derivatives using Mg-Al hydrotalcite as an efficient Lewis acid catalyst has been developed. Water was used as a green solvent and the reaction gave products in high yields in shorter reaction time and involved easy work up. The reaction works well with both electron deficient and electron rich aldehydes.
