Fray, M. Jonathan published the artcileOn the stereoselectivity of epoxide formation using dimethyloxosulfonium methylide. X-ray structure of (5SR)-5-[(1RS)-1-methyl-2-oxacyclopropyl]pyrrolidin-2-one, Quality Control of 5034-06-0, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1983), 395-401, database is CAplus.
Epoxidation of 5-acetylpyrrolidin-2-one with dimethyloxosulfonium methylide in THF at 20° for 2 h and then 55° for 1 h gave a 78:22 mixture of epoxides I (α-Me, β-Me) (II and III, resp.) whereas in the presence of ZnCl2 a 23:77 mixture of II and III was obtained. The configuration of these epoxides was determined from the NMR spectra of the corresponding carbonate derivatives IV and by x-ray crystallog. anal. of III.
