- Abstract
The preparation of new tail to tail dimers of bridged aminodeoxysugars 2 and 11 is described. The first key step in the synthesis is the formation of the aminomethyl bridge in the carbohydrate-derived monomer 7 which is achieved by silver promoted ring closure of methyl 3-acetamido-6-bromo-2,3,6- trideoxy α-D-glucoside 6. Secondly, olefin metathesis of the corresponding 4-O-allyl glycoside 9 constitutes a powerful tool for dimerization, which allows synthesis of 1,4-butanediol-linked tail to tail neooligosaccharides 2 and 11.
