- One-Pot Synthesis of N-Iodo Sulfoximines from Sulfides
-
This is the first report on the synthesis and characterization of N-iodo sulfoximines. The synthesis was designed as a room temperature one-pot cascade reaction from readily available sulfides as starting compounds, converted into sulfoximines by reaction with ammonium carbonate and (diacetoxyiodo)benzene, followed by iodination with N-iodosuccinimide or iodine in situ, in up to 90% isolated yields, also at a multigram scale. Iodination of aryls with N-iodo sulfoximines, oxidation, and conversion to N-SCF3 congeners have been demonstrated.

- Palladium-Catalyzed Direct α-Arylation of p -Methoxybenzyl-Protected S, S -Dimethylsulfoximine
-
Sulfoximines have recently gained considerable recognition as an important structural motif in the life sciences. This is especially true for (hetero)aryl-substituted S,S-dimethylsulfoximine derivatives, such as the marketed insecticide sulfoxaflor, as well as the clinical candidates PTEFb inhibitor BAY 1143572 and ATR inhibitor AZD 6738 for the treatment of cancer. Herein, the first palladium-catalyzed direct α-arylation of p-methoxybenzyl-protected S,S-dimethylsulfoximine using readily available (hetero)aryl bromides is reported. This new method provides a safe, short, and efficient approach to (hetero)aryl-substituted S,S-dimethylsulfoximine derivatives, an important class of bioactive compounds, demonstrated by application of this methodology to an improved synthesis of PTEFb inhibitor BAY 1143572.

- Method for synthesizing sulfoximine compounds from thioether
-
The invention discloses a synthetic method for synthesizing sulfoximine compounds from thioether in one step and application thereof. The synthetic method disclosed by the invention comprises the step of mixing the thioether, an ammonia source and an organic solvent together for carrying out an oxidizing reaction in the presence of an oxidizing agent, thereby obtaining the corresponding sulfoximine compounds. According to the invention, one-step synthesis of the sulfoximine compounds from the thioether is realized for the first time. In recent years, the sulfoximine structure is introduced into the existing drug molecules or high-activity compound molecules, and many high-activity molecules at the clinical stage and listed drug molecules appear. According to the method disclosed by the invention, the drug molecules containing the sulfoximine structure are produced, and the industrial cost can be greatly reduced; and moreover, the synthetic method provided by the invention has the advantages of being high in yield, readily available in raw materials, simple in conditions, simple in reaction equipment, easy in industrialized production, and the like. The structural formula is as shown in the specification.

- Iodinane- and metal-free synthesis of N-cyano sulfilimines: Novel and easy access of NH-sulfoximines
-
The synthesis of W-cyanosulfilimines can readily be achieved by reaction of the corresponding sulfides with cyanogen amine in the presence of a base and NBS or l2 as halogenating agents. Oxidation followed by C-N bond cleavage affords synthetically useful WH-free sulfoximines.
