Summary of NMR results. Deviations between calculated chemical shifts of 1 and its reported experimental shifts (left). Deviations between calculated chemical shifts of 4 and the previously reported experimental shifts for serlyticin-A (center) and newly determined experimental shifts for 4 (right). Deviations of less than 6 ppm for 13C and less than 0.3 ppm for 1H shifts are considered acceptable.13–15 Deviations exceeding these limits are bolded. For unsymmetrical dimers, shifts for the two monomers were averaged.
