DOI: 10.1016/j.tet.2021.132423
Abstract: Abstract The sialylation using sialyl donor with 2,6-dimethylbenzyl (DMBn) ester at C-1 carboxy group rapidly proceeded with good α-selectivity to yield sialyl-N-acetylgalactosaminylated 9-fluorenylmethoxycarbonyl (Fmoc) serine unit. The unit was used for the solid-phase peptide synthesis… read more here.
