A rapid, simple synthesis and purification of abscisic Acid glucose ester.
1986
A simple and rapid technique was developed to synthesize abscisic acid glucose ester. The free acid of abscisic acid (ABA) was combined with CsHCO 3 to form the Cs salt of ABA. The Cs salt of ABA was then combined with acetobromo-α-d-glucose tetraacetate, and the tetraacetate derivative of abscisic acid glucose ester was formed. Acetate groups were selectively removed from the glucose moiety with a crude enzyme preparation derived from Helianthus annuus seeds. Abscisic acid glucose ester was purified via silica gel column chromatography and identified by micro NMR.
