The Lewis acid catalyzed reaction of 5-chloro-1,3-cycloheptadiene 4 with silyl enol ethers yields α-cycloheptadienyl substituted carbonyl compounds in high yield.Since 4 is easily prepared from cycloheptatriene, and the cycloheptadienyl cation 3 is preferably attacked at 3-position, this reaction opens an efficient access to 3-substituted 1,4-cycloheptadienes.
