1-Bromo-4-(S-methylsulfonimidoyl)benzene (BD336512) 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.
Domino cross-coupling/cyclization reactions of N-propargyl sulfoximines and 2-iodophenols or 2-iodoanilides are catalyzed by a cooperative palladium/copper system to provide benzo[b]furan and indole derivatives in good to excellent yields. The reactions occur under mild conditions and tolerate a wide variety of functional groups. E.g., in presence of PdCl2(PPh3)2 and CuI, cross-coupling/cyclization of N-propargyl sulfoximine derivative (I) with 2-IC6H4OH gave 90% benzofuran derivative (II).
Synthesis of N-Methyl-2-indolyl- and N-Methyl-2-benzo[b]furyl-Substituted Sulfoximines by Pd/Cu Co-Catalyzed Domino Cross-Coupling/Cyclization Reactions. Recommended basis is Sulfoximine, Bioisosteric. Products is: https://www.ambeed.com/products/1621962-30-8.html, 50578-18-2
