Dear Ray,
Having read your poster I have a couple of points I would
like to make:
1. You say that epimerisation of 3 occurs to give epi-3 in the text
but the scheme shows structure 2, is this correct?
2. Prompted by 1. can you get compound 2 to epimerise under forced
conditions (relative to compd 3)?. If not then it seem to me that the
stereochemistry of the nitrile containing carbon must be important wrt
the mechanism (although I cannot see why).
