Although more correctly described as ent-clerodanes, the term neoclerodane is preferred by most, as proposed by Rogers et al. (Rogers, D.; Unal, A. A.; Williams, D. J.; Ley, S. V.; Sim, G. A.; Joshi, B. S.; Ravindranath, K. R. J. Chem. Soc., Chem. Commun. 1979, 97.), and is commonly used to describe all structures with this framework.

Assuming that the stereochemistry of the anomeric center in the natural product is the thermodynamic isomer, we should observe the stereochemistry upon oxidative cleavage and subsequent cyclization should be equivalent to that seen in 3.
