Nie, Xingliang published the artcileIntroducing A New Class of Sulfonyl Fluoride Hubs via Radical Chloro-Fluorosulfonylation of Alkynes, Name: 2-Phenylethanethiol, the publication is Angewandte Chemie, International Edition (2021), 60(40), 22035-22042, database is CAplus and MEDLINE.
A new and powerful class of sulfonyl fluoride hubs, β-chloro alkenylsulfonyl fluorides (BCASF) (E)/(Z)-RC(R1)=CHS(O)2F (R = n-Pr, Ph, naphthalen-2-yl, cyclohexyl, thiophen-3-yl, etc.; R1 = Cl, Ph, pyrrolidin-1-yl, thiophen-3-yl, etc.), which can be constructed via radical chloro-fluorosulfonyl difunctionalization of alkynes RCCR1 under photoredox conditions was introduced. BCASF mols. exhibit versatile reactivities and well undergo a series of transformations at the chloride site while keeping the sulfonyl fluoride group intact, including reduction, Suzuki coupling, Sonogashira coupling, as well as nucleophilic substitution with various nitrogen, oxygen, and sulfur nucleophiles. By using BCASF as a synthetic hub, a wide range of sulfonyl fluorides becomes readily accessible, such as cis alkenylsulfonyl fluorides, dienylsulfonyl fluorides, and ynenylsulfonyl fluorides, which are challenging or even not possible to synthesize before with the known methods. Moreover, further application of BCASF to the late-stage modification of peptides and drugs is also demonstrated.
