Polymer-assisted solution-phase synthesis of glycosyl chlorides and bromides using a supported dialkylformamide as catalyst.
Glycosyl halides are a very valuable and versatile group of synthetic intermediates widely used in carbohydrate chemistry for the ready functionalization at the anomeric carbon. Thus, glycosyl halides can be easily converted into O-glycosides, C-glycosides, or glycals via the generation of intermediate anomeric carbocations, radicals, or cabanions. Because of their moderate stability, glycosyl ...
