FeCl 3 -Promoted regioselective ring-opening reactions of cyclopropyl trimethylsilyl ethers, obtained by SmI 2 reduction followed by silylation with Me 3 SiCl of bromoalkyl ketones and acyl chloride, were performed. Eventually, the sequential reduction and oxidation reactions starting from bromoalkyl ketones to give ring-expanded enones were achieved in one-pot.
