✦ Synopsis

El-1,2-Hydroxyiminoketones containing an appropriately positioned and substituted oZefinic group afford high yie2cl.s of various 5-and B-membered heteroeyclic systems when reacted with trifluoroacetic acid. Under the same conditions inappropriately substituted unsaturated 1,24y&oxyiminoketones fragment by means of the second order Beckmann process.
