Abstract
The tuberostemonine molecule, C22H33NO4, consists of a pyrrolidine, a cyclohexane, an azepine and two furan rings. Each furan ring adopts th e envelope conformation while the pyrrolidine ring takes that of a twi st-chair. The cyclohexane and the azepine rings have chair conformatio ns. In the title compound, the vicinal rings are cis-fused, whereas in a previously investigated tuberostemonine (m.p. 359-361 K) a trans-fu sion of the pyrrolidine and the cyclohexane rings was found.
