Abstract |
Euphornin, isolated from EuphoYbia heiioscopia L.(Toudai Gusa in Japanese),is atoxic diterpene having antitumor activity. Euphornin is a highly oxygenatedditerpene containing two double bond included in a 12-membered ring. Oxidativecleavage of both double bonds afforded two segments, the C1-C5・C12-C15 segmentand the C6-C11 segment, which would be key intermediates for total synthesis ofeuphornin. Previously, we reported that the degradation reaction of euphornin hasbeen carried out to afford the C1-C5・C12-C15 segment which is expected to becoupled with the C6-C11 segment giving rise to euphornin. In the present paper,new degradation reaction of euphornin has been carried out to afford the desiredcompound having the C1-C5・C12-C15 segment, which was then converted to thesynthetic key intermediate.
