The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: 2-Bromo-6-(bromomethyl)naphthalene( cas:305798-02-1 ) is researched.SDS of cas: 305798-02-1.Ye, Wenchao; Zhang, Laijun; Ni, Chuanfa; Rong, Jian; Hu, Jinbo published the article 《Stereoselective [3+2] cycloaddition of N-tert-butanesulfinyl imines to arynes facilitated by a removable PhSO2CF2 group: synthesis and transformation of cyclic sulfoximines》 about this compound( cas:305798-02-1 ) in Chemical Communications (Cambridge, United Kingdom). Keywords: stereoselective cycloaddition butanesulfinyl imine aryne removable difluorophenylsulfonylmethyl; difluorinated cyclic sulfoximine preparation; preparation difluorinated cyclic sulfinamide. Let’s learn more about this compound (cas:305798-02-1).
An unprecedented [3+2] cycloaddition between N-tert-butanesulfinyl imines and arynes provides a stereoselective method for the synthesis of cyclic sulfoximines. Not only does the difluoro(phenylsulfonyl)methyl group play an important role in facilitating the cycloaddition reaction, it can also be removed or substituted through the transformation of the difluorinated cyclic sulfoximines, e.g. I, to cyclic sulfinamides, e.g. II.
