Abstract In the presence of water and a catalytic amount of InBr3, intramolecular trans-addition of silyl enolates derived from ketones and an aldehyde to alkynes proceeded smoothly to give 4 to 7-membered carbocycles bearing an acyl group. When carboxylic anhydrides were used as electrophiles instead of water, the cyclized products could be functionalized with an additional acyl group.
