Total Synthesis of (+/-)-Cycloeudesmol and (+/-)- Epicycloeudesmol
Chen, Edward Y.
, p. 3245 - 3250 (1984)
The first total synthesis of both (+/-)-cycloeudesmol (3) and (+/-)-epicycloeudesmol (4) is described.The key stereospecific construction of the bicyclohexane system was conveniently achieved by an olefin-ketocarbene cyclization reaction.
