Utility of glycosyl phosphites as glycosyl donors-fructofuranosyl and 2-deoxyhexopyranosyl phosphites in glycoside bond formation
摘要:
The discussion of the ease of generating glycosyl donor properties in the important sugar categories (aldoses, ketoses, deoxy sugars, sugar uronates, and 3-deoxy-2-glyculosonates) implies that phosphites of ketoses and deoxy sugars, respectively, should be valuable donors. This is exhibited for fructofuranosyl phosphite 2 and for 2-deoxyhexopyranosyl phosphites 14a,b which are readily available and generally provide disaccharides in high yields.
