(d)$\mathrm{X}=$ Option (d) structure 1 of 2, ABC26OR0892 $\mathrm{Y}=$ Option (d) structure 2 of 2, ABC26OR0892
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
The cuprate adds 1,4, giving 3,3-dimethylcyclohexanone enolate, and MeI alkylates C-2 to give X = 2,3,3-trimethylcyclohexanone. In the Baeyer–Villiger step the more substituted α-carbon (CHMe) migrates, so O ends up next to it (d).
