3-Silyloxytetrahydrofurans via sulfoxonium ylide reactions with α-silyloxyepoxides

α-Silyloxyepoxides were found to undergo sulfoxonium ylide induced ring-opening, followed by silyl-migration and intramolecular SN2 reaction, resulting in 3-silyloxytetrahydrofurans. Studies on the scope and utility of this transformation are described.
