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.

An oxidative cross-coupling reaction between aldehydes and sulfoximines involving dual C-H/N-H functionalization was developed. This reaction process is facilitated by a simple copper catalyst (1 mol% loading) and tert-Bu hydroperoxide (TBHP) as the oxidant and proceeds under mild reaction conditions to afford a series of valuable N-acylated sulfoximine derivatives in excellent yields.
