Facioselectivity at Stereotopic Molecular Faces

We now examine, in detail, aspects of facioselectivity at the eleven fundamental paired molecular faces - hi-he, e, and di-dr. These results are summarized in Table 12.3. 

Reactions of homotopic faces hi and h4 are always afacioselective, with 

In sum, (a) hi-he can all be afacioselective, with any reagent (b) only h2,h3,h5,he can be nonfacioselective, with any reagent and (c) none of them can be facioselective, with any reagent.
