DMDP-related iminosugars have been synthesized from cyclic nitrones 12, 13, 18, ent-18 or 23 and nitrone-derived aldehydes 20 or ent-20. The fluorinated iminosugars were assayed against various glycosidases, and ent-8 showed moderate but selective α-L-rhamnosidase inhibition. Difluoro or trifluoro units influenced the inhibitory activities of iminosugars in a more complex manner than single fluoro substitution
