Abstract
The crystal and molecular structure of the spiro dihydrofuran diterpene nepetaefolin (1) has been determined. The structure was solved by direct methods analysis of data from a crystal with space group P212121 and a = 11.092 ± 0.002 Å, b = 11.484 ± 0.002 Å, c = 15.379 ± 0.003 Å, Z = 4 and density ρcalcd = 1.371 g/cm3. An anisotropic large-block least-squares refinement converged to a conventional residual of R = 0.042 for 2015 reflections recorded with Cu Kα radiation on an automatic four-circle diffractometer. The effects of the considerable steric interactions in this molecule on the bond lengths are discussed.
