Orthogonal Glycosylations

SCHEME 5.15 Synthesis of D-glucosamine oligomers by orthogonal glycosylation. 

The orthogonal glycosylation strategy was also employed in the synthesis of the blood group B determinant [30] and was applied to polymer-supported synthetic strategies [31].

Scheme 4.17 Orthogonal glycosylations of thioglycosides and glycosyl fluorides.

The potential of the mannuronate ester donors in the formation of the p-mannosidic linkage has been demonstrated with the construction of a mannuronic acid alginate pentamer using a convergent orthogonal glycosylation.64... 

Fig. 6. Orthogonal glycosylation the glycosyl donor is attached to the solid support alternating coupling with a thioglycoside and a glycosyl fluoride acceptor.

An orthogonal glycosylation strategy was outlined in 1994 by Ogawa (21) that featured the use of two glycosyl donors...
