Synthesis of γ-Lactams via Pd(II)-Catalyzed C(sp3)-H Olefination Using a Self-Cleaving Polyfluoroethylsulfinyl Directing Group

A monodentate directing group, 2-chlorotetrafluoroethylsulfinylmide (-NHSOCF2CF2Cl), for inert C(sp3)-H bond activation is reported. This directing group shows efficient ability in Pd(II)-catalyzed C(sp3)-H olefination. The desired olefination products un

Synthesis and identification of solution-stable sulfenic acids: Perfluoroalkanesulfenic acids

Taking advantage of the strong electron-withdrawing effect of perfluoroalkyl groups, solution-stable perfluoroalkanesulfenic acids were synthesized for the first time by Cope-type elimination of the corresponding imines; the acids were identified by 1H NMR, 19F NMR, and IR spectroscopy and mass spectrometry. Trapping reagents were utilized to capture the in situ generated sulfenic acids, which provided further experimental evidence for the formation of these fluorinated sulfenic acids. Owing to the strong electron-withdrawing effect of perfluoroalkyl groups (R f), solution-stable perfluoroalkanesulfenic acids are synthesized by Cope-type elimination of the corresponding imines at 80 °C; the acids are identified by 1H NMR,19F NMR, and IR spectroscopy and mass spectrometry. Trapping agents are used to capture the in situ generated sulfenic acids, which provides the experimental evidence. Copyright

Per(poly)fluoroalkanesulfinamides assisted diastereoselective three-component inverse-electron-demand aza Diels-Alder reaction

A highly diastereoselective three-component inverse-electron-demand aza Diels-Alder reaction assisted by per(poly)fluoro-alkanesulfinamides is presented, providing a broad spectrum of highly functionalized piperidine derivatives with excellent endo/exo an

Optically pure polyfluoroalkanesulfinamides: Synthesis and application as promising and monitorable chiral auxiliaries

Efficient synthesis of enantiopure polyfluoroalkanesulfinamides (PFSAs) has been achieved. Their application as novel chiral auxiliaries with an electron-withdrawing and 19F NMR monitorable polyfluoroalkyl group was initially demonstrated in an

Diastereoselectivity-switchable and regiospecific hetero Diels-Alder reaction of N-sulfinylper(poly)fluoroalkanesulfinamides with dienes

N-Sulfinylper(poly)fluoroalkanesulfinamides reacted readily with dienes in methylene chloride at -78°C to give the corresponding cycloadducts with complete regioselectivities and good diastereoselectivities. The diastereoselectivity of the reaction was switchable to the opposite under the catalysis of Lewis acids such as TiCl4 and SnCl4.
