Abstract
Description
Technical Field
[0001] The present invention relates to a chiral sulfilimine lipid compound, and in particular to a chiral sulfilimine lipid compound, a preparation method thereof and an application thereof. Background Art
[0002] Chiral sulfur compounds are of great significance in asymmetric synthesis and drug discovery. Over the past few years, extensive research has focused on catalytically controlled synthesis of S-chiral compounds. Currently, research on the catalytic synthesis of chiral sulfilimines focuses primarily on constructing sulfur chirality, particularly utilizing transition metal catalysis or organocatalytic strategies to achieve highly enantioselective synthesis of sulfilimines with varying aromatic or alkyl substituents. These breakthroughs not only address key challenges in the synthesis of sulfilimines but also provide important tools for drug discovery and organic synthesis.
[0003] Among the numerous chiral sulfur compounds, chiral sulfimidates, as aza analogs of sulfinates, are universal precursors of various azasulfur stereoisomerization centers. Their azasulfur stereoisomerization centers can provide additional modification sites due to their N-substitution, form more hydrogen bonds, and enhance structural diversity, thereby greatly improving the pharmacological parameters and physicochemical properties of some candidate drugs.
[0004] However, the asymmetric catalytic synthesis of chiral sulfimidates has long been a research challenge in the field of asymmetric catalysis, lacking effective asymmetric catalytic synthesis strategies. In 2023, Japanese chemists achieved the stereospecific synthesis of chiral sulfimidates via asymmetric O-isopropylation of chiral sulfenamides (Angew. Chem. Int. Ed. 2023, 62, e202300637). Recently, Wu Xingxing's group at Guizhou University achieved the asymmetric catalytic synthesis of chiral sulfimidates via dynamic kinetic resolution of racemic sulfenamides (Angew. Chem. Int. Ed. 2025, e202500170). In recent years, sulfur-functionalized sulfenamides have gradually attracted the interest of chemists at home and abroad, providing a new approach for the asymmetric catalytic synthesis of chiral sulfilimines (J.Am.Chem.Soc.2023,145,6310;Org.Lett.2023,25,2830;J.Org.Chem.2023,88,16116.). Therefore, the development of new catalytic strategies for the synthesis of chiral sulfilimines is highly desirable and is expected to advance the development of chiral sulfilimine pesticides and pharmaceuticals.

[0030] Example 1: Synthesis and characterization of compound 4a
[0031]
[0032] Step 1: To a 10 mL dry reaction tube, add sulfenamide 2a (0.10 mmol), isobutanol 3a (0.20 mmol), (100 mg), the metal-centered chiral cobalt(III) complex anion Λ-(S,S)-1a (0.01 mmol); ultra-dry tetrahydrofuran (1.0 mL) was added to a reaction tube and stirred at -40°C for 30 minutes. N-iodosuccinimide (0.20 mmol) was then added to the reaction tube in one portion and the entire system was reacted at -40°C for 36 hours. The reaction was quenched by adding aqueous Na2S2O3 solution and then separating the organic layer from the aqueous phase. After quenching the reaction, the aqueous phase was extracted with ethyl acetate (3 × 5.0 mL). The organic layer was dried over anhydrous sodium sulfate.
