Conversion Of Enamines Research Articles

ChemInform Abstract: Visible Light Induced Photocatalytic Conversion of Enamines into Amides.

A series of enamines were photocatalytically cleaved to produce amide products under simple visible-light irradiation from a 45 W household light bulb. Mechanistically, the reactions appear to involve photosensitized formation of a singlet oxygen intermediate and a subsequent [2+2] cycloaddition event.

A New Reaction Type in the Conversion of Enamines with 1,4‐Diphenyl‐2‐butene‐1,4‐dione to Give Cage Compounds

Spherical oxygenated heteropolycycles 3, containing stable acetal groups of a hitherto unknown type, can be obtained with surprising ease by the action of simple enamines 1 (n = 1–4) on the diketone 2. An ene addition is followed by a thermal [2 + 2 + 2] cycloaddition of the two carbonyl groups to the enamine double bond. Mor = morpholino.
