In 1976, we reported' an unidentified sugar (yersiniose) as a component of the O-specific side-chain polysaccharide from the lipopolysaccharide (LPS) of Yersinia pseudotuberculosis VI serovar, which was not detected in the LPS of Y. pseudotuberculosis I-V serovars 2. The sugar was shown to be relate

Methyl L-sibirosaminide and N-acylkansosamine were synthesized via the same intermediate, methyl 4-amino-4,6-dideoxy-2,3-O-isopropylidene-3-C-methyl-cY+mannopyranoside ( 7), from L-rhamnose in 7 and 10 steps, respectively. Conversion of 7 into the title compounds was performed by N-methylation or N-
## Abstract A stereodivergent synthesis of differently configured C2βbranched 4βamino sugar derivatives was accomplished. The Lewis acid mediated rearrangement of phenylthioβsubstituted 1,2βoxazines delivered glycosyl donor equivalents that can directly be employed in glycosidation reactions. Treat
The synthesis of brain glutamate requires an amino group donor that is efficiently transported into the brain and that is readily transaminated. The branchedchain amino acids (BCAA), particularly leucine, play this important role. The uptake of leucine across the blood-brain barrier is faster than a
