Page/Page column 21-23, (2012/11/14)
The present invention relates to the field of catalytic hydrogenation and, more particularly, to a process for the reduction by hydrogenation, using molecular H2, of a C6-C20 conjugated dienal into the corresponding deconjugated enal, characterized in that said process is carried out in the presence of a catalytic system comprising at least a base and at least one complex in the form of a rhodium complex comprising a C34-C60 bidentate diphosphine ligand (L2) coordinating the rhodium.

When the β-acyloxy esters (±)-10 and (±)-II were exposed to the lipase OF-360 from Candida rugosa or immobilized lipase OF-360 in a water- saturated organic solvent, the hydrolyzed product (8aS)-6 was obtained in high chemical (40%) and optical (>99%ee) yields. The absolute structure of (8aS)-6 was confirmed by the fact that (8aS)-6 was converted into an authentic sample γ-keto nitrile (8aS)-17. Treatment of the diol (±)-12 with isopropenyl acetate in the presence of the lipase Godo E-4 from Pseudomonas sp. provided the unchanged (8aR)-12 (89% ee) in 42% yield.
