On October 5, 2012, Ivashkin, Pavel; Couve-Bonnaire, Samuel; Jubault, Philippe; Pannecoucke, Xavier published an article.COA of Formula: C8H15NO2 The title of the article was Asymmetric synthesis of cyclopropanes with a monofluorinated quaternary stereocenter. And the article contained the following:
New chiral fluorinated reagents (N-(dibromofluoroacetyl)oxazolidinones) were easily synthesized and used in an asym. cyclopropanation process. The Michael initiated ring closure reaction provided chiral cyclopropanes bearing a fluorinated quaternary stereocenter. Various electron-deficient alkenes can be used to efficiently obtain chiral polysubtituted fluorinated cyclopropanes in good yields. Moderate to very good cis/trans ratios were obtained with a high level of diastereoselectivity for each isomer. The experimental process involved the reaction of (S)-4-Isopropyl-5,5-dimethyloxazolidin-2-one(cas: 168297-86-7).COA of Formula: C8H15NO2
