Abstract The crystal structure of 11-acetoxy-4-deoxyasbestinin B (C22H34O4,M r=362.49) crystallized in the orthorhombic space groupP212121 witha=10.923(5)Å,b=11.127(5)Å,c=17.047(5)Å,V=2072(3)Å3,Z=4,D x=1.163g/cm−3. MoK α radiation was used for data collection at room temperature. The finalR=0.042 for 2464 observed reflections. The stereochemical assignments of the molecule from the 2-D NMR data are verified totally by the overall geometry of the molecule obtained from the X-ray diffraction analysis.
