Beschreibung

Allgemeine Beschreibung

D-(-)-Quinic acid, a plant metabolite, is chiral building block used in multistep chemical synthesis of natural compounds.

Anwendung

D-(−)-Quinic acid can be used as:      

• A chiral selector electrolyte along with copper(II) sulfate. This electrolyte is utilized in chiral resolution DL-tartaric acid by ligand-exchange capillary electrophoresis method.        
• A starting material in the synthesis of stereoisomers of 3,4,6-trihydroxyazepanes, 7-hydroxymethyl-3,4,5-trihydroxyazepanes, and 3,4,5-trihydroxyazepanes, as potential inhibitors of glycosidase.        
• A precursor for the preparation of trihydroxy piperidine derivatives and (+)-proto-quercitol glycosidase inhibitors.

D-(-)-Quinic acid has been used as a standard to determine the composition of organic acids in bitter gentian teas and in developing cranberry fruit by HPLC. It may be used in the preparation of 3,4-O-isopropylidene-3(R),4(S)-dihydroxycyclohexanone.
