The exterior frontier orbital extension model (EFOE model) has shown that p
i-facial stereoselection in nucleophilic additions of 2,3-endo,endo-disubst
ituted bicyclo[2.2.1]heptan-7-ones (1) is dictated by the three terms of th
e Salem-Klopman equation steric effect, electrostatic interaction and orbit
al interaction.
