J. Am. Chem. Soc., 116, 5662 (1994)
Compounds #8a and #8b in this
publication have the same chemical shift for the C=O group at
170.46ppm. Whereas the value in compound #8a is in the correct
expectation range, the CO of #8b should be expected around 195-197ppm
instead of 170.46ppm.
The original data as given in the
paper are shown - the deviation between the experimental value
and the predicted value is approximately 26ppm. It can be assumed, that
this
error is simply caused by a typo.
