Visible-light-promotedE-selective synthesis of α-fluoro-β-arylalkenyl sulfidesviathe deoxygenation/isomerization process

Regioselective synthesis of α-fluoro-β-arylalkenyl sulfides has been established withgem-difluoroalkenes and sodium sulfinates in a transition-metal-free manner. A series of control experiments were executed to demonstrate thiol radicals and anions as the proposed intermediates. Notably, regioselectiveZ→Eisomerization was achieved under green light irradiation in the absence of a photoinitiator.

Visible-Light-Driven Sulfonation of α-Trifluoromethylstyrenes: Access to Densely Functionalized CF3-Substituted Tertiary Alcohol

Reported herein is a visible-light-induced sulfonation of α-trifluoromethylstyrenes with sodium sulfinates, which provides a series of α-trifluoromethyl-β-sulfonyl tertiary alcohols. This new synthetic protocol is enabled by a charge-transfer complex between oxygen and sulfinates, featuring broad substrate scope and scalability. Excellent functional group compatibility and chemoselectivity render this method suitable for sulfonation of pharmaceutically relevant molecules. In the presence of D2O, deuteriotrifluorinated products were also obtained, further demonstrating the flexibility and synthetic potentials of this strategy.

Synthesis of arylboronates via the Pd-catalyzed desulfitative coupling reaction of sodium arylsulfinates with bis(pinacolato)diboron

The desulfitative borylation reaction of sodium arylsulfinates with bis(pinacolato)diboron or bis(neopentylglycolato)diboron under palladium catalysis has been developed, allowing selective C-B bond formation to give arylboronates with a range of functional groups in moderate to good yields under mild reaction conditions. A gram-scale preparation as well as the cascade Suzuki-Miyaura cross-coupling of arylboronates demonstrated the potential practical utility in organic synthesis.

Sulfonyl pyridine amide derivatives and preparation method thereof

The invention relates to a Sulfonyl pyridine amide derivatives and a preparation method thereof; the preparation method comprises the following steps: adding a compound as shown in a structural formula (II), a compound as shown in a structural formula (III), an oxidant, an additive and a heterogeneous biomass supported copper catalyst into a reaction container, adding a solvent, and carrying out astirring reaction at room temperature; and after the reaction is finished, filtering, extracting, concentrating, separating and purifying to obtain the sulfonyl pyridine amide derivative with the structural formula shown in the formula (I). The synthesis method of the sulfonyl pyridine amide derivatives is scientific and reasonable, and a series of sulfonyl pyridine amide derivatives are synthesized by a green and efficient synthesis method by adopting a heterogeneous biomass copper-loaded catalyst for catalytic reaction.

Diastereoselective Monofluorocyclopropanation Using Fluoromethylsulfonium Salts

Diarylfluoromethylsulfonium salts, alternatives to freons or advanced fluorinated building blocks, are bench stable and easy-to-use sources of direct fluoromethylene (:CHF) transfer to alkenes. These salts enabled development of a trans-selective monofluorinated Johnson-Corey-Chaykovsky reaction with vinyl sulfones or vinyl sulfonamides to access synthetically challenging monofluorocyclopropane scaffolds. The described method offers rapid access to monofluorinated cyclopropane building blocks with further functionalization opportunities to deliver more complex synthetic targets diastereoselectively.

Switchable regioselection of C-H thiolation of indoles using different TMS counterions

A switchable regioselectivity in C-H thiolation reaction by simply swapping the counteranions of TMS is reported here for the first time. An exclusive C3-H thiolation of indoles with sodium arylsulfinates was achieved in the presence of TMSCl as a promoter. In contrast, with the use of TMSOTf instead of TMSCl under otherwise identical conditions, a regiospecific C2-H thiolation of indoles was realized with the same set of substrates.
