TL;DR: Poitediol as mentioned in this paper is an unusual sesquiterpene with a trans-fused bicyclo(6.30)undecane, which belongs to the chiral, monoclinic space group P/sub 2/ with a = 9.412(6), b = 17.721(3)A, and..beta.. = 114.69(4)/sup 0/
Abstract: The compound was isolated from ethanol extracts of the red seaweed Laurencia poitei(Lamouroux) Howe by extensive liquid chromatography on ..mu..-Porasil. The structure of the compound, established by x-ray crystallography, belongs to the chiral, monoclinic space group P/sub 2/ with a = 9.412(6), b = 17.489(8), c = 9.721(3)A, and ..beta.. = 114.69(4)/sup 0/. A calculated and observed density of 1.09 g/cm/sup 3/ (Z = 4) indicated that two molecules of C/sub 15/H/sub 26/O/sub 2/ form the asymmetric unit. Poitediol is an unusual sesquiterpene with a trans-fused bicyclo(6.30)undecane. The five-membered ring is in the envelope conformation with C(8) as the flap(0.615A) removed from the plane of atoms C(1), C(11), C(10), and C(9). The eight-membered ring does not assume any simple conformation. Molecular distances and angles are generally in agreement with accepted values. A computer-generated perspective drawing is also included.
