Oriented Clicking (DOC) is a discovery method geared toward the rapid synthesis of functional libraries. It combines the best attributes of both classical and modern click chemistries. DOC strategies center upon the chemical diversification of core “SuFExable” hubs—exemplified by 2-Substituted-Alkynyl-1-Sulfonyl Fluorides (SASFs)—enabling the modularassembly of compounds through multiple reaction

we study sulfuramidimidoyl fluorides, a class of weak electrophiles that undergo sulfur(vi) fluoride exchange chemistry. We show that equilibrium binding of a sulfuramidimidoyl fluoride to a protein can allow nucleophilic attack by a specific amino acid side chain, which leads to conjugate formation. We incubated small molecules, each bearing a sulfuramidimidoyl fluoride electrophile, with human cell
