Sharpless and coworkers provides a powerful tool for modular assembly of molecular linkages. 9 This new embodiment of click chemistry has been used in the fields of synthetic chemistry, 10 chemical biology, 11 drug discovery 12 and polymer synthesis. In particular, click reactions of sulfonimidoyl fluorides with O-and N-nucleophiles provide efficient synthesis of sulfonimidamides and sulfonimidate esters. Sharpless and coworkers reported DBU can catalyze SuFEx of sulfonimidoyl fluorides and aryl silyl ethers to give sulfonimidate esters in high yields. In 2020, Zuilhof and coworkers documented an interesting silicon-free SuFEx click reaction of sulfonimidoyl fluorides and free phenols. They found that 1.0 equivalent can efficient mediate the coupling of sulfonimidoyl fluorides and phenols to give sulfonimidate esters in high yields within several minutes. Recently, the same group further reported 16a Lewis acid mediated enantiospecific synthesis of sulfonimidamides. They found that l.0 equivalent of Ca (NTf 2 ) 2 can promote the SuFEx click reaction of sultonimidoyl fluorides and aromatic amines to produce sulfonimidamides in high yields. Very recently, our group reported 17a an organocatalytic SuFEx reaction of sulfonyl fluorides.
