Spirocyclopropyl pyrrolidines as a new series of alpha-L-fucosidase inhibitors

Bioorg Med Chem. 2006 Jun 15;14(12):4047-54. doi: 10.1016/j.bmc.2006.02.005. Epub 2006 Feb 20.

Abstract

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 glycononitriles with subsequent cyclization. Five new polyhydroxypyrrolidines so-obtained have been evaluated for their ability to inhibit 16 glycosidases. One of them exhibits selective inhibition of alpha-L-fucosidase from bovine kidney (Ki=1.6 microM, competitive).
