Amino peracetylation

Sharpless reaction of the enantiomeric alkenes (47) produced the precursors for 2-amino-2-deoxy-o -D and -L-carba-glucopyranoses. These compounds were converted into the penta-7V,0-acetates by the following sequence. Replacement of the bromo group with an acetate ion, treatment with sodium in liquid ammonia, and peracetylation. [Pg.66]

N. catarrhalis,560 N. perflava,559 Moraxella duplex and Micrococcus calco-aceticus,443 and Escherichia coli,420 Vicari and Kabat,45 in studies of blood-group oligosaccharides, and Hellerqvist and colleagues,53 in an examination of the common core-polysaccharide of Salmonella typhimurium, have used similar methods. The examination of amino sugars as their peracetylated aminodeoxyalditols has also been used by Liideritz and colleagues72 to establish the occurrence of 4-amino-4-deoxy-L-arabinose in Salmonella lipopolysaccharides, and has been extended to aminodeoxyheptoses by Williams and Perry.561... [Pg.86]

Griggs and coworkers343 showed that the decomposition554 of the peracetates of aminodeoxyalditols is minimized if the temperature of the injection port is held below 220°. Furthermore, they identified the product formed from peracetylated 2-amino-2-deoxy-D-glucitol... [Pg.86]

First the amino functionality is protected and the carbohydrate is peracetylated. [Pg.249]
