Ru-catalyzed asymmetric hydrogenation of racemic aldehydes via dynamic kinetic resolution: Efficient synthesis of optically active primary alcohols

A highly efficient asymmetric hydrogenation of racemic α-arylaldehydes via dynamic kinetic resolution has been developed by using [RuCl2(SDPs)(diamine)] complexes as catalysts, providing chiral primary alcohols in excellent enantioselectivities. Copyright

Catalytic asymmetric hydrogenation of aldehydes

Racemic α-arylaldehydes provide the corresponding primary alcohols via dynamic kinetic resolution in excellent enantioselectivities and yields upon hydrogenation using a Noyori ruthenium catalyst; for example, the biologically active (S)-enantiomer of the non-steroidal anti-inflammatory drug ibuprofen could be synthesized via catalytic enantioselective hydrogenation of aldehyde 1f followed by oxidation with potassium permanganate in 76% isolated yield and 96: 4 er.

Catalytic asymmetric couplings of ketenes with aldehydes to generate enol esters

(Chemical Equation Presented) With a little help from the ferrocenyl catalyst ((-)-1), a wide array of α-arylalkanoic acid derivatives can be produced from the catalytic asymmetric coupling of ketenes with aldehydes (see scheme). The enol esters are readily transformed into other useful families of compounds such as carboxylic acids and alcohols.

149. Synthesis of Enantiomerically Pure Ferrocenes from Glycofuranosyl-cyclopentadienes, Synthetic Equivalents of (Alkoxyalkyl)fulvenes

Cyclopentadienyl C-glycosides ( = glycosyl-cyclopentadienes) have been prepared as latent fulvenes.Their reaction with nucleophiles leads to cyclopentadienes substituted with (protected) alditol moieties and, hence, to enantiomerically pure metallocenes.T
