Abstract

All the theoretically possible, foru diastereoisomeric pairs, α,α (2A and 2B), α,β (3A and 3B), β,α (4A and 4B), and β,β (5A and 5B), of pseudo-trehalose, composed of d-glucopyranose and pseudo-d- or l-glucopyranose, have been synthesised by coupling of the appropriately protected pseudo-α- (6) and -β-dl-glucopyranoses (9) with d-glucopyranose derivatives (10 and 11) in the presence of trimethylsilyl trifluoromethanesulfonate. Elucidation of the structures and absolute configurations of the pseudo-disaccharides was based on the 1H-n.m.r. spectra of their octa-acetates and the optical rotations. None of the pseudo-trehaloses inhibited trehalase.
