Visible-light photoredox-promoted desilylative allylation of α-silylamines: An efficient route to synthesis of homoallylic amines
A facile and efficient synthesis of homoallylic amines by visible-light photoredox-promoted desilylative allylation of α-silylamines with allylic sulfones is described. A variety of α-silylamines derived from anilines, cyclic and acyclic alkyl amines reacted with a serious of mono or disubstituted allylic sulfones well to provide homollylic amines in good to high yields under very mild reaction conditions.
Photocyclization of 4-(Dialkylaminno)-2-aryl-1-butenes
Irradiation of 4-(dialkylamino)-2-aryl-1-butenes gave cyclization products, 3-methyl-3-arylpyrrolidines, in high yields.These styrylamines formed fluorescent intramolecular exciplexes, but studies based on Stern-Volmer quenching for the fluorescence and t
