U. Voigtmann et S. Blechert, Variable and stereoselective synthesis of azasugar analogues by a ruthenium-catalyzed ring rearrangement, ORG LETT, 2(25), 2000, pp. 3971-3974
A novel ruthenium catalyzed ring opening/ring closing tandem metathesis rea
ction with a catalytic transfer of stereocenters from a ring to an olefinic
chain is described. This ring rearrangement serves as the key step in the
stereoselective synthesis of the new azasugar analogues 1 and 2.
