Synthesis of N-Imidoyl and N-Oxoimidoyl Sulfoximines from 1-Alkynes, N-Sulfonyl Azides, and Sulfoximines. Recommended basis is Sulfoximine, Bioisosteric. Products is: https://www.ambeed.com/products/1621962-30-8.html, 50578-18-2

1-Bromo-4-(S-methylsulfonimidoyl)benzene (BD336512) is a building block containing a sulfoximine group. Several CDK and ATR inhibitors have exemplified the utilization of the NH sulfoximine group as abioisostere for a sulfonamide group to overcome the main project hurdles of aqueous solubility, sulfonamide-mediated off-target activity and IP. Moreover, its NH group could be expediently further functionalized through Buchwald-Hartwig coupling reaction and multifarious nucleophilic reactions.. Recommended Products is: 4381-25-3 and 83730-53-4.

N-Imidoylation of sulfoximines is developed from a Cu-catalyzed three-component reaction from 1-alkynes, N-sulfonyl azides, and sulfoximines in THF at room temperature under air. In addition, N-oxoimidoylation of sulfoximines is accessed from a Cu-catalyzed three-component reaction from 1-alkynes, N-sulfonyl azides, and sulfoximines in THF at room temperature followed by a Cu-catalyzed oxidative reaction at 50 ¡ãC under air, producing N-oxoimidoyl sulfoximines.
