چکیده
The structure of the racemic title compound, C(10)H(15)NO(4), consists of a tricyclic skeleton comprising a six-membered piperidine ring and five-membered isoxazolidine and tetra-hydro-furan rings. The piperidine ring adopts a distorted chair conformation, while the isoxazolidine and tetra-hydro-furan rings have envelope conformations.

The present paper describes a total synthesis of racemic β-chamigrene, a sesquiterpene with a spiro[5.5]undecane carbon framework. Compared with previously reported β-chamigrene syntheses, we were able to reduce the total number of reaction steps, which also resulted in a significant improvement of the overall yield. The commercially available ketone 6-methylhept-5-en-2-one was transformed by k...
