1-Iminotetrahydrothiophene 1-oxide (BD00963737) 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 metal-free and operationally simple N-arylation of NH-sulfoximines with aryne precursors is reported. E.g., in presence of KF/18-crown-6 in THF, reaction of o-TMSC6H4OTf and PhSMe(:O):NH gave 72% PhSMe(:O):NPh. Transition metal-free reaction conditions and shorter reaction times are the highlights of the present method. The mild optimized condition was also suitable with enantiopure substrates.
