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.
A copper-catalyzed methodol. for the preparations of N-aroylated sulfoximines from methylarenes was herein demonstrated. The transformation proceeded with the assistance of external oxidant tert-Bu hydroperoxide, requiring for no addnl. solvents or ligands. The good compatibility and high efficiency of the newly developed protocol were well described by 21 examples and up to 91% yields. Moreover, the protocol was proved by the control reactions to proceed through a radical pathway.
