The irradiation of N-alkanoyll-β-enaminones lead to the formation of spiranic β-lactams which undergo C-N bond cleavage during chromatography on alumina giving cycloalkenones functionalized at position 3. This new rearrangement has been applied to the synthesis of α-amino-β,γ-unsaturated amides in one step and gives convenient yields.
Intramolecular [2 + 2] photocvcloaddition of N-alkenovl-β-enaminones

The photolysis of cyclic N-alkenoyl β-enaminones is described. In general, a very regio- and stereoselective intramolecular [2 + 2] photocydoaddition was observed. The limitations of the reaction process are discussed. The main competitive reaction, which
