Sulfonyl fluoride motif can be used as a connector for the assembly of -SO2- linked small molecules with proteins or nucleic acids. This new click chemistry approach through sulfates is a complimentary approach to using amides and phosphate groups as linkers.
This article details the latest progress in synthesizing alkylsulfonyl fluorides through different approaches that utilize photoredox catalysis, electrocatalysis, transition-metal catalysis, and organocatalysis. The alkylsulfonyl fluorides thus prepared could be utilized further in sulfur(VI) fluoride exchange (SuFEx) click reactions.
