Visible-Light Photocatalytic Bicyclization of 1,7-Enynes toward Functionalized Sulfone-Containing Benzo[a]fluoren-5-ones

A new visible-light photocatalytic arylsulfonylation and bicyclization of C(sp3)-tethered 1,7-enynes with sulfinic acids has been developed, delivering functionalized sulfone-containing benzo[a]fluoren-5-ones with generally good yields. This Eosin Y-catalyzed approach makes use of visible light as a safe and eco-friendly energy source to drive cascade cyclization reactions, resulting in continuous multiple bond-forming events including C–S and C–C bonds to efficiently construct polycyclic-linked alkyl aryl sulfones. (Figure presented.).

Styrene sulfone NLRP3 inflammasome inhibitor, preparation method and application thereof

The invention relates to the field of styrene sulfone compounds and NLRP3 inhibitors, and particularly provides a styrene sulfone NLRP3 inflammasome inhibitor, a preparation method and application thereof, wherein the inhibitor is represented by a formula (1), n is selected from 0 and 1, X is selected from N and O, R1 is selected from different electron withdrawing or electron donating substituents, and R2 is selected from different fat or aromatic substituents. According to the invention, it is verified that the compounds represented by the general formula have NLRP3 inhibitory activity.

Visible-Light-Induced Radical Cascade Cyclizations of 1,7-Enynes with Sulfinic Acids: Direct Access to Sulfonated Chromanes and Sulfonated Tetrahydroquinolines under Metal-Free Conditions

Visible-light-induced strategy to access sulfonated chromanes and sulfonated 1,2,3,4-tetrahydroquinolines via a radical cascade cyclization of 1-(arylethynyl)-2-(vinyloxy)benzenes and N-allyl-2-(arylethynyl)anilines with aromatic and aliphatic sulfinic acids has been developed. In the presence of TBHP (7.5 mol%) as an oxidant and Eosin Y (3.0 mol%) as a photocatalyst, the reactions undergo smoothly to afford the corresponding products in good yields at room temperature under metal-free conditions. This transformation features low loading of TBHP, mild reaction conditions, simple operation, broad functional-group tolerance, and good yields of products. (Figure presented.).

Microwave-accelerated Pd-catalyzed desulfitative direct C2-arylation of free (NH)-indoles with arylsulfinic acids

The rapid and efficient direct C2-arylation of free (NH)-indoles with arylsulfinic acids proceeded through a microwave-accelerated palladium-catalyzed desulfitation reaction. By using PdCl2 as a catalyst, silver acetate as an oxidant, and H2SO4 as an additive, arylsulfinic acids with both electron-donating and electron-withdrawing groups underwent desulfitative coupling with an array of free (NH)-indoles, thereby selectively providing C2-arylindoles in good yields. From C2 shining sea: The direct C2-arylation of free (NH)-indoles with arylsulfinic acids proceeded through a Pd-catalyzed desulfitation reaction. In the presence of an oxidant and an additive, 2-arylindoles were selectively afforded in good yields. Copyright

Preparation of optically active ortho-chloro- and ortho-bromophenyl sulfoxides

The preparation of the diastereomerically pure menthyl (S)-2-chloro- and (S)-2-bromophenyl sulfinates by esterification of the corresponding sulfinic acids with (1R,2S,5R)-(-)-menthol and recrystallization/epimerization is reported. The two sulfinates have been converted into enantiomerically pure aryl, vinyl and alkyl sulfoxides by reaction with organomagnesium reagents. These sulfoxides are useful chiral auxiliaries to control the stereochemical outcome of radical reactions.
