On February 28, 1983, Fray, M. Jonathan; Thomas, Eric J.; Wallis, John D. published an article.HPLC of Formula: 5034-06-0 The title of the article was On the stereoselectivity of epoxide formation using dimethyloxosulfonium methylide. X-ray structure of (5SR)-5-[(1RS)-1-methyl-2-oxacyclopropyl]pyrrolidin-2-one. And the article contained the following:
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. The experimental process involved the reaction of trimethyloxosulphonium chloride(cas: 5034-06-0).HPLC of Formula: 5034-06-0
The Article related to epoxidation acetylpyrrolidinone stereoselectivity, pyrrolidinone acetyl epoxidation stereoselectivity, methyloxiranylpyrrolidinone preparation configuration crystal structure, oxiranylpyrrolidinone methyl structure and other aspects.HPLC of Formula: 5034-06-0
