Using in situ generated tert-butyl sulfonylcarbamate from tert-butyl chlorosulfonylcarbamate and diisopropylethylamine, a catalyst-free, mild aminosulfonylation of electron-rich (hetero)arenes was reported.
This review highlights the advances from the past decade that provide readers with essential tools for designing and implementing radical sulfonylation using SO2 surrogates in organic synthesis.
This review aims to systematically consolidate the recent advances in palladium-catalyzed sulfonylation via SO2 insertion, elucidate the underlying reaction mechanism, and highlight some unsolved challenges in this segment.
A reductive cross-coupling strategy for the synthesis of sulfone-containing oxindoles was presented. Moreover, using amines instead of alkyl bromides, a palladium-catalyzed domino cyclization/aminosulfonylation was also established.
A review of recent advances in visible-light-mediated synthetic strategies for generation of SO2-X (X = F, O, N) bonds to give sulfonyl compounds.
