The anchoring sites of the spacer and the reaction temperature have a remarkable effect on the regio- and stereo-selectivity of intramolecular macrocyclic glycosylation reactions of several template linked monosaccharides leading to macrocyclic disaccharides and thence to disaccharides.

Intramolecular glycosylation of several glucose derived glycosyl donor and acceptors that are linked, at O-6 and O-2 respectively, to a bifunctional spacer results in the regio- and stereo-controlled formation of 13-membered macrocyclic glycosides which can be easily converted to disaccharides.
