Abstract

Ten kinds of 5-[(indol-3-yl)-methyl]-2,2-dimethyl-1,3-dioxane-4,6-dione derivatives were synthesized by the three component condensation reaction of indole with aldehydes and 2,2-dimethyl-1,3-dioxane-4,6-dione using succinimide-N-sulfonic acid cerium as catalyst under solvent-free and ultrasonic irradiation. The results indicated that the yields ranged from 68.9% to 96.7%, when using 3% (molar fraction) succinimide-N-sulfonic acid cerium and reacting at 30℃ for 30 to 60 min. Furthermore, a proposed reaction mechanism for the reaction catalyzed by succinimide-N-sulfonic acid cerium was speculated. The main advantages of the present procedure were milder conditions, shorter reaction time and higher yields. Further study showed that succinimide-N-sulfonic acid cerium was environmentally friendly and reused for six times without any noticeable decrease in the catalytic activity.
