been synthesized from precursors 18a and 18b, obtained in both enantiomeric forms from d-ribose. Out of these polyhydroxy piperidine azasugars, 22, 39 and 20 were found to be potent as well as selectiveinhibitors of alpha-glucosidase with K(i) values ranging as low as 1.07 microM, 16.4 microM, and 88.2 microM, respectively. Replacement of the hydroxy methylene moiety of (K(i) 33% at 1 mM) by an amino

[GRAPHICS]A new synthetic strategy has been developed for a general approach toward the synthesis of a variety of 1-N-iminosugar-type glycosidase inhibitors utilizing precursors developed by the PET-mediated cyclization of alpha-trimethylsilylmethylamine radical cation to a tethered pi-functionality.
