Stereospecific Synthesis and Characterization of Aminoglycoside Ligands from Diethylenetriamine
摘要:
A convenient synthetic route to diglycosylamines derived from diethylenetriamine and D-glucose, D-galactose, D-allose, or L-fucose is presented where the stereochemically pure product is easily isolated and crystallized as a hydrochloride salt. The diglucosyl diethylenetriamine analogue is characterized by X-ray crystallography, and the chloride ion is shown to stabilize the compound in the crystalline state. These ligands provide simple and efficient routes to various diastereomeric metal N-glycoside coordination complexes that are currently being studied by mass spectrometry.
