title: Sulfonium ylide epoxidation reactions: methylene transfer.
abstract: Using a D-mannitol derived chiral sulfide, terminal epoxides are formed in up to 76% ee; the first example of double asymmetric induction in a sulfonium methylide epoxidation is reported and an improved method of generating sulfonium ylides is detailed.
