Synthesis of ?-fucosyl glycosides and disaccharides using 4-methoxybenzyl (Mpm) protected fucosyl donors
摘要:
The 4-methoxybenzyl (Mpm) group removable by selective oxidation was applied as a non-neighbouring-group-active protection of fucose hydroxy functions in the stereoselective synthesis of alpha-fucosides of acceptors containing double bonds sensitive to hydrogenation. With this aim, the synthesis of the alpha-fucosyl chloride (4) carrying the acid-sensitive Mpm protection was elaborated.
