Sequential C-H activation enabled expedient delivery of polyfunctional arenes

Modular construction of polyfunctional arenes from abundant feedstocks stands as an unremitting pursue in synthetic chemistry, accelerating the discovery of drugs and materials. Herein, using the multiple C-H activation strategy with versatile imidate esters, the expedient delivery of molecular libraries of densely functionalized sulfur-containing arenes was achieved, which enabled the concise construction of biologically active molecules, such as Bipenamol.

Ortho-position imine ester or cyano substituted aryl thioether derivative, and preparation method and application thereof

The invention belongs to the technical field of organic synthesis, and particularly relates to an ortho-position imine ester or cyano substituted aryl thioether derivative, and a preparation method and an application thereof. The structural formula of the ortho-position imine ester or cyano substituted aryl thioether derivative is represented by formula (I) or formula (I'). The preparation methodcomprises the following steps: selecting an imine ester substrate and different substituted disulfide coupling reagents, mixing the reactants with a catalyst, an oxidant and a halide ion capturing agent under air atmosphere and alkaline conditions, and carrying out an aromatic ring ortho-position carbon-hydrogen bond activation reaction to obtain the ortho-position imine ester or cyano substitutedaryl sulfide derivative. The preparation method is simple and easily available in substrate and simple to operate, and achieves the efficient synthesis of the aryl thioether derivative of ortho-position imine ester or cyano group through the regulation of a catalytic system; and the product can be applied to later-stage derivatization reaction of drug molecules such as probenecid, and synthesis potential is provided for rapid construction of thioether derivatives with bioactive molecule libraries.

Facile synthesis of 1,2-thiobenzonitriles: Via Cu-catalyzed denitrogenative radical coupling reaction

A Cu-catalyzed synthesis of 1,2-thiobenzonitriles via oxidative C-N cleavage of 3-aminoindazoles followed by radical coupling with thiols is developed. A diverse array of 1,2-thiobenzonitriles were obtained in good yields with wide substrate scope. Notably, this is the first example of denitrogenative radical coupling with 3-aminoindazoles.

Synthesis of Functionalized Diaryl Sulfides by Cobalt-Catalyzed Coupling between Arylzinc Pivalates and Diaryl Disulfides

An efficient protocol for the cobalt-catalyzed preparation of diaryl sulfides from solid organozinc pivalates and commercially available diaryl disulfides is reported. This cross-coupling proceeds at room temperature and displays a good functional group tolerance, allowing the preparation of a diversity of symmetrical or asymmetrical diaryl sulfides in 60-95% yield.

Activation of aryl thiocyanates followed by aryne insertion: Access to 1,2-thiobenzonitriles

Palladium-catalyzed activation of carbon-sulfur bonds allows aryne insertion into aryl thiocyanates to generate new C-SAr and C-CN bonds in one step. The readily available starting materials make this method efficient in generating a variety of 1,2-thiobenzonitriles. By choosing an oxygen atmosphere the yields are increased and side reactions are minimized.

Iridium and phosphine promoted C-F bond activation: The C-S cross-coupling of aryl fluorides with diaryl disulfides to synthesize thioethers

Carbon-fluorine bond is the strongest known single bond to carbon and proved very difficult to cleave. An iridium and phosphine promoted C-F bond activation was developed, for the first time achieving the C-S cross-coupling reaction of disulfides with aryl fluorides using iridium complex. The corresponding monoarylthiolation products were obtained at moderate to good yields. Thus, it represents a new method for the synthesis of aryl sulfides through C-F bond activation.

Rhodium-catalyzed substitution reaction of aryl fluorides with disulfides: P-orientation in the polyarylthiolation of polyfluorobenzenes

In the presence of a catalytic amount of RhH(PPh3)4 and 1,2-bis(diphenylphosphino)benzene, an aromatic fluoride, an organic disulfide (0.5 equiv), and triphenylphosphine (0.5 equiv) reacted in refluxing chlorobenzene to give an aryl sulfide in high yield. Since triphenylphosphine trapped fluoride atoms forming phosphine difluoride, both organothio groups of the disulfide reacted effectively, and the fluoride substituent reacted more readily than the chloride and bromide. The reaction of hexafluorobenzene and a diaryl disulfide gave 1,4-diarylthio-2,3,5,6-tetrafluorobenzene, 1,2,4,5-tetraarylthio-3,6-difluorobenzene, and hexaarylthiobenzene in a stepwise manner; pentafluorobenzene gave 1-arylthio-2,3,5,6-tetrafluorobenzene; 1,2,3,4-tetrafluorobenzene gave 1,2-diarylthio-3,6-difluorobenzene; and 1,2,4,5-tetrafluorobenzene gave 1,4-diarylthio-2-5-difluorobenzene. The polyarylthiolation reaction of polyfluorobenzenes exhibited a strong tendency to form 1,4-difluorobenzenes. Copyright
