Total synthesis of both enantiomers of 15-oxopuupehenol methylendioxy derivatives
摘要:
The total synthesis of both enantiomers of puupehenol and 15-oxopuupehenol as methylenedioxy derivatives is described. The key steps of the synthesis are the regioselective transformation of 10 to 11 and the stereoselective cyclization of 12 to 13. (C) 1997 Elsevier Science Ltd.

Compounds 7–8, monoterpenic analogues of the marine metabolites puupehenone (1) and puupehedione (2), were prepared from the easily available β-cyclocitral (10) and the aryllithium derived from 11 and 12. 8 showed antitumoral activity 4–10 times higher than that for the natural products. 8 showed antitumoral activity 4–10 times higher than that of natural puupehedione.
