Samarium Iodide Induced Intramolecular C-Glycoside Formation: Efficient Radical Formation in the Absence of an Additive

With pyridylsulfonyl instead of phenylsulfonyl leaving groups sugar derivatives such as 1 undergo radical cyclization promoted by SmI2. 5‐exo Cyclization finally results in C‐glycosides of type 2.
