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 synthesis of N-propargylsulfoximines RCCCH(R1)N=S(O)R2R3 [R = C6H5, 4-ClC6H4, (CH2)2C6H5, etc.; R1 = H, C6H5, cyclopentyl, 2H-1,3-benzodioxol-5-yl, etc.; R2 = CH3, C6H5, 2-BrC6H4, etc.; R3 = CH3, C6H5, 4-ClC6H4CH=CH; R2, R3 = -(CH2)4-] was developed through a copper-catalyzed coupling of alkynes RCCH, aldehydes R1CHO and NH-sulfoximines R2R3S(O)NH. The reaction requires no co-catalyst or ligand and shows a wide substrate scope with moderate to good yields.
