A series of 10‐substituted‐3,3,6,6‐tetramethyl‐9‐aryl‐3,4,6,7,9,10‐hexahydroacridine‐1,8(2H,5 H)‐dione derivatives 2 were synthesized by reaction of compounds 1 with amines. The compounds 1 were effectively prepared by 5,5‐dimethylcyclohexane‐1,3‐dione and aldehydes in the presence of a little amount of L‐proline as catalyst at room temperature. All the compounds were characterized by IR, MS, and 1H
