Photocyclization of 4-(dialkylamino)-2-aryl-1-butenes
摘要:
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 the photoreaction suggested that the emissive exciplexes did not participate in the photoreaction.
