5-Fluoro derivatives of 4-epi-isofagomine as D-galactosidase inhibitors and potential pharmacological chaperones for GM1-gangliosidosis as well as Fabry's disease.

Abstract Electrophilic fluorination of an exocyclic methoxymethylene enol ether derived from N-tert-butyloxycarbonyl-1,5-dideoxy-1,5-imino-3,4-O-isopropylidene- d - erythro -pent-2-ulose ( 11 ) provided the 5-fluoro derivative of the powerful β-galactosidase inhibitor 4- epi -isofagomine ( 8 ). This structural alteration, in combination with N-alkylation, led to considerably improved α-galactosidase selectivity. New compounds may serve as leads en route to new pharmacological chaperones for Fabry's disease.
