The tridecasaccharide glycan domain of lipooligosaccharidesfrom the opportunisticpathogenMycobacteriumkansasii was synthesized. The target (see structure) possesses structural motifs that make its synthesis a formidable challenge, including rare monosaccharides, an asymmetrically substituted trehalose residue and a base-sensitive amide side chain. The study provides a strategy for synthesizing

The enantioselective synthesis of from ethyl (S)-lactatevia methyl (S)-3-methoxymethoxy-2-oxobutanoate15 is described. The stereogenic centre at C-2 was established by a one-pot, dual enzyme catalysed hydrolysis of the ester (by a lipase) and reductiveamination of the ketone of 15 (with leucine dehydrogenase) to give, after deprotection, acid as a single diastereomer in 93% yield.
