• Marque: Biosynth
• Description: 7b-Hydroxy cholesterol 3b-acetate is an allylic compound that is catalyzed by molybdenum, which eliminates the acetyl group at position 7 to form a double bond with the 3-position. The reaction temperature of 7b-hydroxy cholesterol 3b-acetate can be increased to high temperatures (i.e., >100°C) for the elimination process, and allylic acetates are obtained as products. The reaction starts with the addition of hexacarbonyl, which leads to a diene intermediate. This is then eliminated by adding acetamide in presence of high concentration of acetic acid and catalytic amounts of molybdenum. The low yield and efficiency, however, are major drawbacks of this process.
