The compound below undergoes E2 elimination using LDA as a
strong base, and there is only one observed product.
Draw the observed product and the theoretically possible isomer
that we don’t see.
Draw the mechanism to produce both.
Draw an energy coordinate diagram for this reaction including
the two low
energy conformations of the starting material (hint: chairs),
the observed product, and the theoretically possible product. Make
sure all relative energies are accurate (ground state and
transition state).
