The acidity controlled indolylation reaction of 3,3-bis(ethylthio)acrylates to selectively yield 3,3-di(indol-3-yl)acrylates and 3-(indol-3-yl)-3-oxopropanoates was studied. It showed that 3,3-di(indol-3-yl)acrylates were obtained in good yield under diluted acidity condition when 3,3-bis(ethylthio)acrylates reacted with indole derivatives, while the reaction performed under concentrated acidity produced 3-ethylthio-3-(indol-3-yl)acrylate, which were easily hydrolyzed to supply 3-(indol-3-yl)-3-oxopropanoates in good yield under acid condition.

Key words: α-oxo ketene dithioacetals, 3,3-bis(ethylthio)acrylates, indole derivatives, necleophilic substitution
