New electrophiles targeting thiols in a reversible covalent manner

Reversible covalent electrophiles with the advantages of both reversible and covalent interactions receive much attention in the fields of chemical biology and medicinal chemistry. Here, we report two electron-deficient olefins activated by amide and ester, amide-substituted acrylamide and methyl ester-substituted acrylamide, targeting thiols in a reversible covalent manner. Two electron-deficient olefins activated by amide and ester, amide-substituted acrylamide and methyl ester-substituted acrylamide, targeting thiols in a reversible covalent manner were reported.
