摘要：

The absolute stereochemistry of aplyroseol-1 (1), a diterpenoid isolated from Aplysilla rosea Barrois, has been established as (5S, 7R, 8S, 9R, 10S, 13R, 14R, 15R) by determining the crystal structure of the p-bromobenzoyl derivative (3) by X-ray diffraction methods. The structure was refined to a residual of 0.032 for 1451 independent observed reflections. The crystals are monoclinic, space group P2(1), a 6.668(8), b 20.04(1), c 10.974(3) Angstrom, beta 98.04(7)degrees.
