(S-Methylsulfonimidoyl)benzene (BD302898) 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: 83730-53-4 and 1621962-30-8.
A metal-free reaction system consisting of TEMPO and PhI(OAc)2 for the oxidative C-N coupling of benzoxazoles with NH-sulfoximines had been developed to obtain arylsulfoximines I [R1 = H, 5-Cl, 7-Br, etc.; R2 = Me, Et, n-Bu, Bn; R3 = Ph, 4-FC6H4, 2-BrC6H4, etc.]. The reaction could proceed under ambient atm. without any metal catalyst at room temperature to afford the corresponding 2-iminoazoles in moderate to high yields.
TEMPO/PhI(OAc)2-mediated Direct Sulfoximination of Benzoxazoles under Metal-free Conditions. Recommended basis is Sulfoximine, Bioisosteric. Products is: https://www.ambeed.com/products/50578-18-2.html, 145026-07-9
