A short and efficient protecting group-free synthesis of isotopically labeled 20-[18O]-ingenol has been developed. Based on a highly selective (only one out of four hydroxy groups) Mitsunobu reaction of ingenol with 18O2-acetic acid and subsequent methanolysis, this route yielded the desired 20-[18O]-ingenol in high yield and chemical and isotopic purity.
已经开发了一种短而有效的无同位素保护的同位素标记的20- [ 18 O]-烯醇的合成。基于丁香酚与18 O 2-乙酸的高选择性(仅四个羟基中的一个)Mitsunobu反应和随后的甲醇分解,该路线可高产率,化学和同位素纯度生成所需的20- [ 18 O]-烯醇。
