C-H Activation of Methyl Arenes in the MnO2-Mediated Aroylation of N-Chlorosulfoximines. 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.

An investigation into the reactivity profile of N-halogenated sulfoximines has led to the development of a new method for the synthesis of N-aroylated sulfoximines, e.g., I. This protocol involves the manganese oxide promoted C-H activation of Me arenes to form an aroyl intermediate which then reacts readily with N-chlorosulfoximines to form a series of valuable aroyl sulfoximine derivatives in high yields.
