Iridium-Catalyzed Dynamic Kinetic Isomerization: Expedient Synthesis of Carbohydrates from Achmatowicz Rearrangement Products

A highly stereoselective dynamic kinetic isomerization of Achmatowicz rearrangement products was discovered. This new internal redox isomerization provided ready access to key intermediates for the enantio- and diastereoselective synthesis of a series of naturally occurring sugars. The nature of the de novo synthesis also enables the preparation of both enantiomers.

A divergent approach to 3-azido-2,3,6-trideoxy-l-hexoses from rhamnal

An alternative strategy has been developed for producing 3-azido-2,3,6-trideoxy-l-hexoses, protected forms of daunosamine, ristosamine, acosamine, and epi-daunosamine. This method involved BF3·OEt2-induced peroxidation of rhamnal to
