Abstract
The nonreducing tetrasaccharide terminus of Globo H has been assembled in good yield and excellent stereocontrol exclusively by using mild and moisture stable agents such as Yb(OTf)(3) and acid washed molecular sieves for the activation of glycosyltrifluoroacetimidate donors in the glycosylation steps.

Abstract
In order to expand the repertoire of available oligosaccharide-oligonucleotide hybrids, the on-line solid phase synthesis of oligonucleotides conjugated at the 3'-and/or 5'-end with a preformed disaccharide unit has been performed. The key compound in the synthetic scheme described here is an appropriate phosphoramidite derivative of fully protected sucrose, used in association with a solid support functionalized with DMT-protected sucrose. The sucrose units at both ends of selected oligonucleotide sequences were shown to increase their chemical and enzymatic stability, while not interfering with duplex formation and with the ability of G-rich sequences to adopt a quadruplex structure.

Abstract
[reaction: see text] Commercially available 4 A acid washed molecular sieves (4 A AW 300 MS) are efficient activators of glycosyl trichloro- and N-phenyltrifluoroacetimidates. These promoters allow glycosidation of primary and secondary saccharidic acceptors to be performed in high yield, under very mild conditions and by an experimentally simple procedure. In addition, the recyclability of such promoters also has been demonstrated.
