What epoxide and organometallic reagent are needed to synthesize attachedalcohol?
Reaction of X and phenylacetic acid forms an intermediate Y, which undergoes an intramolecular reaction to yield rofecoxib. Rofecoxib is a nonsteroidal antiinflammatory agent once marketed under the trade name Vioxx, now withdrawn from the market because of increased risk of heart attacks from long-term use in some patients. Identify Y and draw a stepwise mechanism for its conversion to rofecoxib.
