A dihedral angle of 180° is termed and, while an angle of 0° refers to the syn arrangement.

Preliminary investigations to test the rationale with other N-protecting groups (i.e. N-H, N-Me, and N-CHO) were thwarted as attempted oxidation to the meso-dialdehyde led only to the recovery of starting material or decomposition products. Another possibility not investigated by us would be to use a proline derivative incapable of forming such H-bonds such as the methyl ester of L-proline to see if any asymmetric induction occurs at all.

note

One must consider the issues of the E/Z enamine geometry, boat/ chair conformations, synlanti relationship of the carboxylic acid to the olefin, equatorial versus axial placement of substituents, and the issue of H-bond acceptor (Boc carbonyl versus aldehyde) quickly causes the number of reasonable transition states possible to become extremely large. See ref 31 for more detailed discussions.

Based on these rationale, one would expect to obtain (-)-cocaine if D-proline was used instead.
