Mechanistic investigation of the NH-sulfoximination of sulfide. Evidence for ¦Ë6-sulfanenitrile intermediates. Recommended basis is Sulfoximine, Bioisosteric. Products is: https://www.ambeed.com/products/1621962-30-8.html, 145026-07-9

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.

We report a new procedure for the preparation of NH-sulfoximines from sulfides using PIDA as an oxidant and ammonium carbamate as the ammonia source. Excellent yields were obtained with a wide range of sulfides. The formation of acetoxy- and methoxy-¦Ë6-sulfanenitrile as intermediates was proposed, both of which were converted to the NH-sulfoximine by the action of the solvent. The structure of these intermediates was confirmed by 1H, 13C and 15N NMR and HRMS anal.
