摘要:

Both α- and β-anomers of acetylated 5-thio-D-xylopyranosyl azide lead upon thermolysis to a new sugar-derived tetrahydrothiazepine. This compound arises from a ring expansion involving the preferred migration of the ring sulfur atom, which probably assists the decomposition of the azido group with departure of molecular nitrogen.
