An object of the present invention is to provide a method for efficiently chemically synthesizing biomolecules including a nucleotide (nucleic acid), a peptide (protein), or a sugar chain, as representative examples. The present invention provides a method of solid-phase synthesis of sugar chain(s) for synthesizing multiple types of sugar chains in at least one sugar chain synthesis reaction system comprising multiple types of monosaccharide units, which is characterized in that it comprises changing the temperature in the sugar chain synthesis reaction system depending on the temperature rising rate that has been determined based on a decrease in side reaction(s) in the reaction system as an indicator.

examined using N,N-diethylaminosulfur trifluoride (DAST). Although the reaction proceeded without N-bromosuccinimide (NBS), in some cases it was found that the electrophilicity of the Vilsmeier-type electrophilic sulfinium cation species was not sufficient for the activation of certain less-reactive thioglycosides. Here, we report the results of fluorinationreactions of a series of monosaccharides using

The α-aminooxy derivative of the Thomsen–Friedenriech tumor associated carbohydrate antigen has been synthesized in 11 steps utilizing a D-GalN3 acceptor carrying a pre-installed α-N-hydroxysuccinimidyl moiety. The natural α linkage was prepared in high selectivity employing a suitably protected D-GalN3-thioglycoside donor with N-hydroxysuccinimide. With access to α-TF-ONH2, the preparation of the
