Two-Step Azidoalkenylation of Terminal Alkenes Using Iodomethyl Sulfones
The radical azidoalkylation of alkenes that was initially developed with α-iodoesters and α-iodoketones was extended to other activated iodomethyl derivatives.

Direct C–H-sulfonylation of 6-membered nitrogen-heteroaromatics
Heterocyclic sulfones and sulfonamides represent important structural motives in medicinal chemistry and drug development. Therefore, efficient and reliable methods for their construction from simple building blocks are in high demand. Herein we report a

Enantioselective Synthesis of cis-Decalins Using Organocatalysis and Sulfonyl Nazarov Reagents
The first organocatalytic synthesis of cis-decalins using sulfonyl Nazarov reagents is reported. The Jørgensen’s catalyst directs this highly enantioselective synthesis using different cyclohexenal derivatives.

Crystal structure of (2R*,3aR*)-2-phenylsulfonyl-2,3,3a,4,5,6-hexahydropyrrolo[1,2-b]isoxazole
The title compound, C12H15NO3S, was prepared by 1,3-dipolar cycloaddition of 3,4-dihydro-2H-pyrrole 1-oxide and phenyl vinyl sulfone. In the molecule, both fused five-membered rings display a twisted conformation.

Synthesis of New Active Sulfones in the 5-Nitroimidazole Series
We describe here the preparation of new 5-nitroimidazoles which are known to have an efficacy against metronidazole-susceptible and -resistant Giarda, Trichomonas, and Entamoeba spp. The multi-step synthesis uses electron transfer methodology.
