Copper catalyzed N-arylation of sulfoximines with aryldiazonium salts in the presence of DABCO under mild conditions. 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-Arylation of sulfoximines with aryldiazonium tetrafluoroborates was demonstrated in the presence of copper chloride and DABCO. A wide range of aryl and alkyl sufoximines were participated in the coupling reaction with different aryldiazonim salts bearing electron donating and withdrawing groups and provided the desired products in 67-88% yields. The reaction proceeded through a radical mechanism.
