Abstract
A method for the regioselective O-acylation of 3,4-OH free d-glucosamines via stannylene acetal methodology was developed. From fully acetylated 2-N-trichloroacetyl-d-glucosamine, 4-OH free d-glucosamine derivatives bearing orthogonal protecting group patterns were prepared.
Key words
carbohydrates - protecting groups - regioselectivity - stannylene acetals - glycosylaminoglycans
