Abstract:

Ten 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, aldehyde and 2,2-dimethyl-1,3-dioxane-4,6-dione using iodine as the catalyst. The results indicates that the yields range from 71.4% to 97.3% at 30 ℃ for 60~90 min using 5% molar fraction of iodine. Furthermore, a mechanism for the reaction catalyzed by iodine is proposed.

 

Key words: dimethyl-dioxane-dione, iodine, aldehydes, three component condensation reaction
