✦ Synopsis

1,6-Anhydro-b-L-hexopyranoses as valuable building blocks toward the synthesis of L-gulosamine and L-altrose derivatives via the regioselective triflation and benzoylation of 1,6-anhydro-b-L-idopyranose followed by S N 2 substitution with various nucleophiles as key steps is described here.

## Abstract The synthesis of the two ethylthio disaccharide building blocks 10 and 17 was achieved by coupling of fucosyl bromide 9 with the acceptor alcohols 6 and 7 under in situ anomerization conditions. The selectively protected 2‐deoxy‐2‐phthal‐imidoglucose derivative 7 was derived from 6 by u
