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.

The first enantiospecific synthesis of bioactive marine puupehedione (2) and relatedcompounds from (−)-sclareol (11) is reported. The antitumoractivity of these compounds was assayed and compared with that of the natural products.

[GRAPHICS]A new route toward puupehenone-related bioactive metabolites from (-)-sclareol, based on the palladium(II)-mediated diastereoselective cyclization of a drimenylphenol, is described. Utilizing this, the first enantiospecific synthesis of the antitumor and antimalarial (-)-15-oxopuupehenol, together with improved syntheses of (+)-puupehenone, (+)-puupehedione, and (+)-15-cyanopuupehenone, were accomplished.
