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.

The tetracyclic polyfunctional diterpene ingenol (1) is the prototype of many diterpenoid parent alcohols of the ingenane type.Esters of these parent alcohols occur-partly together with esters of polyfunctional diterpene parent alcohols of the tigliane and daphnane type - as irritant, cocarcinogenic and antineoplastic principles in spesies of the family Euphorbiaceae (Spurge).Preparation of 1 from latex of Euphorbia ingens E.May as well as of some functional derivatives of 1 are described. - Key words: Cocarcinogens, Diterpene Esters, Euphorbiaceae, Tumor Promoters
