Photocatalytic iodosulfonylation in ethanol allows the isolation of β-iodovinyl aryl and alkyl sulfones after dilution of the reaction mixture with water and filtration.
An efficient and selective C-H activation method of readily available beta-N-aryl glycosides with various alkynes has been established. Using [Cp*RhCl2](2) as a catalyst and AgSbF6 in DCE, this protocol proved t(o) be general to prepare a variety of 2,3-substituted N-glycosyl indoles in good yields.
