| Abstract: | 4-Hydroxy 3 methyl 2 (2 propynyl) cyclopent 2 enone was prepared from 2 (1 hydroxy 3 butynyl) 5 methylfuran via catalytic rearrangement,and the traditional two step reaction was changed into an one step reaction.As a result,the process was shortened.The optimum teachnological conditions were determined that the reaction was conducted in water, m (catalyst)∶ m (reactant)=3∶100 and the reaction was finished in about 23 h.The yield of 4 hydroxy 3 methyl 2 (2 propynyl) cyclopent 2 enone was 75%,which was higher than the maximum value 68.0% reported in literature. |
