Revised chirality of the acyl group of 8'-O-(3-hydroxy-3-methylglutaryl)-8'-hydroxyabscisic acid.
8'-O-(3-Hydroxy-3-methylglutaryl)-8'-hydroxyabscisic acid is a stable conjugate of the first metabolite of abscisic acid, 8'-hydroxyabscisic acid, that is spontaneously isomerized to phaseic acid. The chirality of the 3-hydroxy-3-methylglutaryl group of the conjugate was revised to S based on an HPLC analysis of the diastereomer derived from mevalonolactone obtained by reduction of the conjugate with lithium borohydride.
