) from mixtures of diterpenoid esters and ingenol esters in a single step. Ingenol isolated by means of this method can be used as a precursor for the synthesis of biologically active ingenol derivatives, such as ingenol-3-angelate and ingenol-3-tigliate.
本发明涉及一种新的方法,用于在单步中从二萜酯和英吉诺酯的混合物中分离出英吉诺醇(
C20H28O5)。通过这种方法分离出的英吉诺醇可以用作合成
生物活性英吉诺醇衍
生物(如英吉诺-3-安吉酸酯和英吉诺-3-提格酸酯)的前体。
