摘要:
Compounds and compositions that have a mannose 6-phosphate receptor or ASGPR binding ligand bound to an extracellular protein binding ligand are provided for the selective degradation of a target extracellular protein in vivo to treat disorders mediated by the extracellular protein.

ABSTRACT The reaction of D-glucal and its derivatives with the electrophilic N-F-fluorination reagents F-TEDA tetrafluoroborate and triflate was studied by means of 19F NMR spectroscopy. In all cases mixtures of 2-deoxy-2-fluoro-D-gluco- and -D-mannopyranose derivatives were formed, the ratio of which was dependent on the nature of the O-protecting groups. Concerning the products arising from the direct

Abstract The regiospecific syn -addition of acetyl hypofluorite to glycals derived from pentopyranoses led to mixtures of stereoisomers. Stereospecific reactions occurred with furanoid glycals, the direction of addition being governed by the nature of the substituent at C-3. Whereas a benzyloxy group caused attack from the opposite, less-hindered face of the double bond, a hydroxyl group induced addition
Modified D-glucose and D-mannose analogs are potentially clinically useful metabolic inhibitors. Biological evaluation of 2-deoxy-2-halo analogs has been impaired by limited availability and lack of efficient methods for their preparation. We have developed practical synthetic approaches to 2-deoxy-2-fluoro-, 2-chloro-2-deoxy-, 2-bromo-2-deoxy-, and 2-deoxy-2-iodo derivatives Of D-glucose and D-mannose that exploit electrophilic addition reactions to a commercially available 3,4,6-tri-O-acetyl-D-glucal.
