2-(4-Ketoalkyl)cyclopentanones, when subjected to the action of 1 M H 2 SO 4 at reflux, undergo ring cleavage and formation reactions to give 4-(1-cyclopentenyl)butanoic acids. When the starting ring is six-membered instead, a bicyclic enone results. Mechanistic discussion and some experimental test
The Cope rearrangement of 1,5-dienes bearing acyl substituents in the 2-position of the diene system is strongly accelerated by protic and Lewis acids. Table 1. Rearrangement of 2-Acyl-1,5-dienes. Starting Material Acid Mol % Acid Conditionsa Productsb Isolated Yield !A CF3C02H 100 15 min, CH2C12 ,&
