We have prepared several ClickFerrophos families and tested for the Cu(I)-catalyzed asymmetric reductive aldol reaction of ketones and aldehydes with an acrylic ester in the presence of phenylsilane. The Cu(I)-ClickFerrophos complex is efficient for the r

(Chemical Equation Presented) An efficient method for the enantioselective tandem reductive aldol reaction of methyl acrylate with aldehydes is reported. By using a copper-(I) precursor and a proper diphosphane ligand, high reactivities can be reached, with TOF up to 40 000 h-1. Taniaphos-based ligands lead to enantioselectivities of up to 97% in the case of the major syn diastereoisomer.
DIRECT, ENANTIOSELECTIVE ALDOL COUPLING OF ALDEHYDES USING CHIRAL ORGANIC CATALYSTS

Nonmetallic, chiral organic catalysts are used to catalyze an enantioselective aldol coupling reaction between aldehyde substrates. The reaction may be carried out with a single enolizable aldehyde, resulting in dimerization to give a β-hydroxy aldehyde,

(1R)- and (1S)-1--(E)-but-2-enyl(tributyl)stannanes (8) and (9), whose configurations were assigned by correlation with (2R)- and (2S)-pentan-2-ol (14) and (15), react stereoselectively on heating with benzaldehyde to give (3S,4S)- and (3R,4R)-4-hydroxy-3-methyl-(Z)-1,2-enol ethers (16) and (18), respectively, the configurations of these products being established by correlation with pseudoephedrine.
