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.

Synthesis of protected siphonodictyal C was achieved via drim-7-en-11-al. Some sesquiterpene quinones and hydroquinones were tested for their pharmacologicalactivities in assays in search of antiproliferative, cytotoxic, antiphlogistic, antirheumatic and anti-inflammatory drugs. Wiedendiol B is a ten times stronger cyclooxygenase-2 inhibitor than the reference compound indomethacine. Cyclooxygenase-2

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.
