Construction of N–S and C–N Bonds from Reactions of Benzofuroxans with DMSO or THF

Novel ring-opening reactions are
achieved employing benzofuroxan
as a new type of iminating or aminating reagent. These diverse transformations
give access to three types of molecular scaffolds, N-aryl dimethylsulfoximines, methanesulfonamides, and hemiaminal ethers,
which are important structural motifs in organic and medicinal chemistry.
The procedures feature solvent-involved reactions, easily available
starting materials, operational simplicity, high atom economy, and
the potential further transformation of nitro group.
