Under the influence of a Lewis acid, 1-siloxycycloalkanecarbaldehydes undergo one-carbonring enlargement reaction to afford the corresponding 2-siloxycycloalkanones in good yields. Regiochemistry of this rearrangement reaction has also been examined, and use of FeCl3 greatly improves the selectivity to give the product arising from migration of a more-substituted site.
