Spirocyclopropyl pyrrolidines as a new series of α-l-fucosidase inhibitors

Polyhydroxy 4-azaspiro[2.4]heptane derivatives (spirocyclopropyl iminosugars) were prepared in four to six steps from readily available protected aldoses. The key step of the reaction sequence involves a titanium-mediated aminocyclopropanation of glyconon

Synthetic access to the first spirocyclopropyl iminosugar

The synthesis of the first spirocyclopropyl iminosugar has been achieved in six steps and 13% overall yield from commercially available 2,3,5-tri-O-benzyl-D-arabinose. The synthesis is based on an efficient two-step reaction involving the titanium-mediate
