Photochemical Cyclisation of Phthalimide Mannich Bases
Coyle, John D.,Newport, Graham L.
, p. 93 - 96 (2007/10/02)
Ultraviolet irradiation of Mannich bases derived from phthalimide, formaldehyde, and a secondary amine leads to cyclised products containing a new imidazolidine ring.The reaction is much less efficient when the secondary amine has an aromatic group adjacent to the nitrogen atom.Exceptionally, the Mannich base derived from 3-pyrroline does not cyclise but undergoes an internal oxidation-reduction reaction to give a substituted pyrrole.
