During the printing process it was detected, that the CPMAS 13C NMR spectrum (Fig. 3) and the melting point recorded for disaccharide 6 originated from a second crystalline phase. The authors sincerely regret that correction of the data has not been possible at that stage any more and apologize for any inconvenience imposed on the readers of the journal. The information given on page 163, lines 4–10 and page 164, line 1 should be replaced by the following: Furthermore, the linewidth of 18 Hz is extraordinarily narrow and TPPM decoupling is required. As indicated in Fig. 3 and Table 4, the following lines can be assigned unambiguously: C-1,1% at 104.9 and 102.9
ppm, C-4,4% at 85.0 and 82.0 ppm, C-6,6% signals at 61.7 and 59.4 ppm and OCH3 at 61.4 and 55.7 ppm. On page 163, Table 4, right-hand column, lines 8–10 should read Chemical shift (ppm) for carbon atom C-1 or C-1% 104.9 106.5 C-4 or C-4% 84.9 85.5 C-6 or C-6%
104.9/102.9 85.0/82.0 61.7/59.4
On page 165, line 17, bottom, the given melting point should be replaced by mp 219 –221 °C. The spectrum in Fig. 3 should be replaced by the following
