METHODS OF SYNTHESIS OF INGENOL AND INTERMEDIATES THEREOF

摘要

The present invention relates generally to methods of synthesis of diterpene heterocylic compounds. More particularly, the present invention relates to efficient methods of synthesis of ingenol (Formula (21), CAS 30220-46-3), from a compound of formula (1). The present invention also provides for various advantageous intermediates along the synthetic route of ingenol. Efficient synthesis of ingenol is important in the design and synthesis of related analogues, such as ingenol-3-angelate.
