    • a and 2′-C was not observed. As with H-H coupling, the value of this 3-bond coupling constant is dependent on the dihedral angle. The absence of cross-peaks is not uncommon and can be understood as the distortion of compounds 2a and 2b from a common conformation.

    • Initial refinement of cocrystal diffraction data (T. Hermann, unpublished data) shows that 2a binds within the A-site essentially the same as the parent 1a. Thus, addition of the conformational restraint does not change the binding mode or grossly alter the ligand-RNA interaction.
