Herein, a novel visible-light photocatalytic radical addition-translocation-cyclization (RATC) approach for the efficient synthesis of sulfonyl-containing azacycles is described. The reaction delivers a wide range of monocyclic, bicyclic and polycyclic azacycles by using easily prepared sodium sulfinates and N-homopropargylic amines as starting materials. Instead of the traditionally used toxic tin reagents and thermally hazardous azos in the RATC process, clean, renewable and sustainable visible light combined with a catalytic amount of photosensitizer is used in this process. Moreover, the successful transformation of some drug derivatives further highlights the potential application of this procedure. The results came from multiple reactions, including the reaction of Thiophene-2-sulfonyl chloride(cas: 16629-19-9Product Details of 16629-19-9)
Thiophene-2-sulfonyl chloride(cas: 16629-19-9) is a member of sulfonyl chlorides. Sulfonyl chlorides are reactive sulfonic acid derivatives similar in properties and reactivity to acid chlorides of carboxylates. The sulfonic acid group, however, is a highly hindered molecule, containing a tetrahedral configuration of substituents. Product Details of 16629-19-9
