Chemical synthesis of cyclodextrins by using intramolecular glycosylation

An efficient synthesis of cyclodextrins (CDs) by using the intramolecular glycosylation is demonstrated. α-CD, an α(1→4)linked hexaglucoside, was prepared via a block condensation of three maltose units. A modified key maltose intermediate as a precursor to both glycosyl donor and acceptor components was prepared in 6 steps starting from maltose. All the glycosylation for chain elongation and cyclization of saccharides was carried out after tethering the donor to the acceptor by the phthaloyl bridge to give the desired saccharides in good yields with complete α-selectivity. δ-CD composed of 9 glucose units was synthesized by the same manner from three maltotriose units.

A short route to malto-trisaccharide synthons: Synthesis of the branched nonasaccharide, 6?-α-maltotriosyl-maltohexaose

A short route to phenyl 1-thio-β-maltotrioside derived building blocks and their use for the synthesis of the branched nonasaccharide, 6?-α-maltotriosyl-maltohexaose, is described. Instead of using glucose and maltose as starting materials, maltotriose wa
