| Abstract: | Using(+)-citronellal as starting material and zinc bromide as catalyst for cyclization,the yield of synthesis of(-)-isopulegol was 70%.The reaction mixture was then fractional distilled to obtain a product containing more than 94%of(-)-isopulegol. (-)-Isopulegol with optical purity of 99.6%can be obtained after recrystallization by acetone. |
