Synthesis of optically active vomifoliol and roseoside stereoisomers

Yamano, Yumiko,Ito, Masayoshi

, p. 541 - 546 (2007/10/03)

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.
