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.

Synthesis of NH-sulfoximines from sulfides by chemoselective one-pot N- and O-transfers

Direct synthesis of NH-sulfoximines from sulfides has been achieved through O and NH transfer in the same reaction, occurring with complete selectivity. The reaction is mediated by bisacetoxyiodobenzene under simple conditions and employs inexpensive N-so

Straightforward Strategies for the Preparation of NH-Sulfox-imines: A Serendipitous Story

Sulfoximines are emerging as valuable new isosteres for use in medicinal chemistry, with the potential to modulate physicochemical properties. Recent developments in synthetic strategies have made the unprotected 'free' NH-sulfoximine group more readily available, facilitating further study. This account reviews approaches to NH-sulfoximines, with a focus on our contribution to the field. Starting from the development of catalytic strategies involving transition metals, more sustainable metal-free processes have been discovered. In particular, the use of hypervalent iodine reagents to mediate NH-transfer to sulfoxides is described, along with an assessment of the substrate scope. Furthermore, a one-pot strategy to convert sulfides directly into NH-sulfoximines is discussed, with N- and O-transfer occurring under the reaction conditions. Mechanistic evidence for the new procedures is included as well as relevant synthetic applications that further exemplify the potential of these approaches. 1 Introduction 2 Strategies to Form NH-Sulfoximines Involving Transition-Metal Catalysts 3 Metal-Free Strategies to Prepare NH-Sulfoximines 4 Mechanistic Evidence for the Direct Synthesis of NH-Sulfoximines from Sulfoxides and Sulfides 5 Further Applications 6 Conclusion.

Transfer of Electrophilic NH Using Convenient Sources of Ammonia: Direct Synthesis of NH Sulfoximines from Sulfoxides

A new system for NH transfer is developed for the preparation of sulfoximines, which are emerging as valuable motifs for drug discovery. The protocol employs readily available sources of nitrogen without the requirement for either preactivation or for met

Synthesis of aryl benzyl NH-sulfoximines

Efficient synthesis and characterisation of a series of aryl benzyl NH-sulfoximines are described. While N-protected versions of aryl benzyl sulfoximines have been previously described, reports of their deprotection are very limited, presumably due to lab
