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 efficient and metal-free method for the construction of ¦Á-diarylmethine imino sulfanones e.g., I using acid-catalyzed 1,6-conjugate addition of sulfoximines e.g., II on para-quinine methides III (R = Ph, 4-fuloropheny, thiophen-2-yl, etc. R1 = Me, t-Bu) (p-QMs) was reported. This method showed broad functional group tolerance and a wide range of substrate scope with good to excellent yield. The excellent protocol exhibits mild reaction conditions with high atom economy. The practicability of the present method was supported by a Gram-scale reaction.
Metal-Free, Acid-Catalyzed 1,6-Conjugate Addition of NH-Sulfoximines to para-Quinone Methides: Accessing to Diarylmethine Imino Sulfanone. Recommended basis is Sulfoximine, Bioisosteric. Products is: https://www.ambeed.com/products/1621962-30-8.html, 145026-07-9
