Two new (6S)-hydroxy-3-oxo-alpha-ionol glucosides, together with corchoionoside C ((6S,9S)-roseoside) and a prenyl glucoside, were isolated from mature fruits of Capparis spinosa. The structures were established on the basis of spectroscopic, chiroptic and chemical evidence. In addition, the 13C-resonance of C-9 was found to be of particular diagnostic value in assigning the absolute configuration at that center in ionol glycosides. The alpha-ionol derivatives are metabolites of (+)-(S)-abscisic acid.
Synthesis of optically active vomifoliol and roseoside stereoisomers

A synthesis of optically active vomifoliol stereoisomers 1-4 and their glucosides, roseoside stereoisomers 5-8, was accomplished via α-acetylenic alcohol 11a or 11b effectively prepared by an asymmetric transfer hydrogenation of α,β-acetylenic ketone 10. Simultaneous separation of these stereoisomers by HPLC was also perfomed.
