Abstract
1-methyl-4-acetyl-1-cyclohexen was achieved in one step synthesis from limonene as the starting material by protecting C1-C2 double with addition and displacement of NBS/CH3OH,followed by oxidation of C8-C9 double with KMnO4/NaIO4 in acetone and water,and subsequent removal of the oxygen atom with zinc and sodium iodide in acetic acid.The purity of product was 99% and the over yield was 70%.The product structure was proved by IR、1HNMR、MS and elementary analysis.
