  A series of prearranged glycosides 4, 9, 14, 16, 22, 28, 33, 41, and 46, having a benzyl-protected 1-thiomannosyl donor linked through its position 6 via malonate and succinate tethers to various positions of glucosamine, galactose, mannose, and rhamnose accepters, were prepared and cyclized to the corresponding disaccharides. The configuration at the anomeric center of the products strongly depended on the position of the tt ther in the acceptor part and could be predicted from the calculated thermodynamic stability of the products. No strong dependence of the diastereoselectivity of the intramolecular glycosylations on the activation conditions and the solvent was observed.

  A series of prearranged glycosides 5, 17, 23, 28, 37 and 41, having a benzyl-protected 1-thiomannosyl donor linked through its positions 2, 3, 4 and 6 via succinate and malonate tethers, respectively, to positions 2, 3, and 6 of a benzyl glucopyranoside acceptor, were prepared by condensation of the respective mannosyl succinates and malonates with suitably protected benzyl glucopyranosides. The prearranged glycosides were intramolecularly coupled under various conditions to give the corresponding, tethered (1 --> 4)-linked disaccharides The yields and anomer ratios of the products of these couplings were interpreted in terms of the thermodynamic stability of the resulting disaccharides. In the case of prearranged glycoside 17, having positions 3 of both the donor and the acceptor linked by a succinate tether, a strong dependence of the diastereoselectivity of the intramolecular glycosylation on the activation procedure was observed. All other cases did not show a significant dependence of the outcome of the anomeric configuration in intramolecular glycosylation on the activation procedure or the solvent.
