Synthesis, Characterization and Crystal Density Modeling of Spiropolycyclic Oxiranes.

Abstract Spiropolycyclic mono- and bis-epoxides 1–6 have been synthesized. The structures of 1–6 have been established unequivocally via application of single crystal X-ray crystallographic methods. The crystal densities of 1–6 (from X-ray crystallographic data) are compared with the results of density predictions.
