Abstract
Novel derivatives of 1,4-dideoxy-1,4-imino-D-mannitol and method for their synthesis from 4,5-anhydro-1-azido-1-deoxy-2,3-O-isopropylidene-D-talitol or its triflate derivative are disclosed. The novel derivatives, 6-fluoro-1,4-imino-1,4,6-trideoxy-D-mannitol and the N-butyl and N-benzyl derivatives of 1,4-dideoxy-1,4-amino-D-mannitol, have useful mannosidase inhibitory activity.
