Versuchsvorschrift
1 gram of Allicin as prepared above (in Example 4) was dissolved in 10 ml of 40% water-acetone solution and the solution was heated between 63–64 C for 4 hours. The reaction mixture was diluted with 30 ml of 50% water-methanol and washed 5 times with 10 ml of n-pentane. The pentane was kept aside for further processing. The lower water-acetone-methanolic layer was then saturated with ammonium sulphate and extracted with 20 ml dichloromethane. The dichloromethane layer was separated, dried with Magnesium Sulphate, filtered and evaporated to yield crude Ajoene.
