Diverse Synthesis of Natural Trehalosamines and Synthetic 1,1′-Disaccharide Aminoglycosides

A general strategy for the diverse synthesis of ten disaccharide aminoglycosides, including natural 2-trehalosamine (1), 3-trehalosamine (2), 4-trehalosamine (3), and neotrehalosyl 3,3′-diamine (8) and synthetic aminoglycosides 4–7, 9, and 10, has been developed. The aminoglycoside compounds feature different anomeric configurations and numbers of amino groups. The key step for the synthesis was the glycosylation coupling of a stereodirecting donor with a configuration-stable TMS glycoside acceptor. Either the donor or acceptor could be substituted with an azido group. The aminoglycosides prepared in the present study were characterized by 1D and 2D NMR spectroscopy.

Desymmetrization of trehalose via regioselective DIBAL reductive ring opening of benzylidene and substituted benzylidene acetals

Trehalose dibenzylidene and substituted dibenzylidene acetals were reductively opened either at O6 or O4 in a regioselective manner by using a DIBAL stock solution prepared in toluene or dichloromethane, respectively, to achieve desymmetrization of the trehalose core. The method was applied to synthesize various biologically important unsymmetrically substituted trehalose glycoconjugates, including a mycobacterial trisaccharide, a 4-epi-trehalosamine analog and a maradolipid.

Syntheses of hepta-, hexa-, and penta-pivalates of trehalose by selective pivaloylation

The order of esterification of the eight hydroxyl groups of trehalose with pivaloyl chloride is HO-6,6' > HO-2,2' > HO-3,3' > HO-4 4'.Under the appropriate conditions of pivaloylation, heptapivalates with either HO-4 or HO-3 free, hexapivalates with eithe
