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.

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.
