Stereocontrolled synthesis of optically active β-D-glucopyranosides of 3-hydroxy-7,8-didehydro-β-ionol

A stereocontrolled synthesis of optically active β-D-glucopyranosides 1-4 of 3-hydroxy-7,8-didehydro-β-ionol utilizing an asymmetric transfer hydrogenation to α,β-acetylenic ketones catalyzed by chiral ruthenium complexes as the key step is described.

Stereocontrolled synthesis of glucosidic damascenone precursors

A stereocontrolled synthesis of optically active β-D-glucopyranosides and glucosidic damascenone precursors was discussed. The method used was asymmetric transfer hydrogenation to α, β-acetylenic ketones catalyzed by chiral ruthenium complexes. To facilitate the confirmation of the stereochemistries of natural glucosides, separation of synthetic four isomers by HPCL was examined.
