Sha, Wanxing published the artcilePhotoredox-Catalyzed Cascade Difluoroalkylation and Intramolecular Cyclization for Construction of Fluorinated γ-Butyrolactones, Product Details of C4H6BrFO2, the publication is Journal of Organic Chemistry (2017), 82(18), 9824-9831, database is CAplus and MEDLINE.
A cascade visible-light photocatalytic difluoroalkylation and intramol. cyclization reaction was developed for the synthesis of difluoroalkylated oxygen heterocycles. The reaction was carried out under mild conditions, affording fluorinated isobenzofuran-1-ones, lactone, and cyclic ethers with up to 97% chem. yields. Furthermore, several types of bromofluoroalkane precursors bearing ester, keto, amido, and phosphate groups could all work well in this reaction, which provides an easy method for the preparation of functionalized difluoroalkylated oxygen heterocycles.
