  Copper-Mediated Fluoroalkylation of Aryl Iodides Enables Facile Access to Diverse Fluorinated Compounds: The Important Role of the (2-Pyridyl)sulfonyl Group

  摘要：

  The (2-pyridyl)sulfonyl group was found to be a multifunctional group in the preparation of structurally diverse fluorinated products. It not only facilitates the copper-mediated (or catalyzed) cross-coupling reaction between a-fluoro sulfone 4a and aryl iodides, but also enables further transformations of the coupling products 2.

  1-tert-Butyl-1H-tetrazol-5-yl fluoromethyl sulfone (TBTSO2CH2F): a versatile fluoromethylidene synthon and its use in the synthesis of monofluorinated alkenes via Julia–Kocienski olefination

  摘要：

  1-tert-Butyl-1H-tetrazol-5-yl fluoromethyl sulfone (TBTSO2CH2F) has been developed as a new and efficient fluoromethylidene synthon for the synthesis of both terminal and internal monofluoroalkenes via Julia-Kocienski olefination reaction. The base-mediated reaction between TBTSO2CH2F and carbonyl compounds (aldehydes and ketones) provided terminal monofluoroalkenes in good yields with moderate E/Z selectivity. The dominance of E- or Z-fluoroalkenes could be controlled by selection of proper reaction solvent and temperature. TBTSO2CH2F reagent was also found to be readily a-alkylated, acylated, and phenylsulfonylated to give corresponding alpha-functionalized fluorosulfones, which could be used in the synthesis of alkyl-, acyl-, and phenylsulfonyl-substituted internal monofluoroalkenes via Julia-Kocienski olefination reactions.

  and novel strategy for the enantioselective syntheses of various iboga alkaloids has been developed. The salient features include a gold-catalyzed oxidation of a terminal alkyne followed by cyclization, a Stevens rearrangement and a tandem sequence that combines the gold-catalyzed oxidation, cyclization and [1,2]-shift. The catharanthine analogs provided by our approach were further converted to the
