a
Numbers refer to protons attached to positions indicated in the structure from Table 2.
b
The values in parentheses are the coupling constants to 13C nuclei (in Hz) except as indicated by superscripts. Chemical shifts are referenced to the residual HOD signal at 4.755 ppm.
c
The values correspond to the coupling constant to 15N.
