    • The configurational instability of 12 and 16 versus 6c is likely due to steric interactions of the endo α′ substituent in the convex bicyclic frameworks. On the basis of the X-ray structure of 23, the ethylcarboxy substituent in 16 presumably also occupies an axial position

    • It should be noted that these values are of roughly equal and opposite sign, which is the principle requirement for our surrogates. However, mimicry of a natural l, l -dipeptide strand would require the synthesis of the enantiomer scaffold starting from d -pyroglutamic acid
