Efficient Glycosylation Using
ODS Adsorption Method Based on the Affinity of Long Alkoxybenzyl
Glycoside
摘要:
p-Oleyloxybenzyl (POB) glycoside, selectively removable with TMSOTf, was developed as a protecting group for the glycosyl acceptor. Activation of the trichloroacetimidate was efficiently accomplished using 20 mol% of Cu(OTf)(2). Purification of the resulting glycoside was rapidly and efficiently accomplished by,in ODS adsorption method based on the significant affinity of long alkyl chains and the ODS. The procedure is particularly useful for convergent oligosaccharide synthesis.
