The totalsynthesis of a sialylated and sulfatedoligosaccharide 1 representative of a structure occurring in respiratory mucins has been accomplished. Our strategy depends upon the employment of 2-naphthymethyl (NAP) protection for hydroxyl functions. Choice of the well-defined sialyl donor 15 was made because of its enhanced reactivity over the parent compound 14 for glycosylation.
