Kelleher, Roger G.,McKervey, M. Anthony,Vibuljan, Pongsak
, p. 486 - 488 (1980)
Anhydrous lithium iodide in ether, tetrahydrofuran, or benzene is an effective reagent for the formation of α,β-unsaturated ketones by condensation of alkyl ketones with enolisable and non-enolisable aldehydes; in the presence of trimethylchlorosilane-triethylamine enone formation is suppressed and high yields of 1,3-hydroxyketones are obtained as their trimethylsilyl ether derivatives.

A new attempt of utilizing solid acid to the cross aldol reaction of silyl enol ethers with aldehydes or acetals has been investigated.Among solid acids employed, the reaction is promoted most effectively by a catalytic amount of aluminium ion-exchanged m
THE FIRST EXAMPLE OF ALDOL REACTIONS BETWEEN TRIMETHYLSILYL ENOL ETHERS AND ALDEHYDES BY THE AID OF RHODIUM COMPLEX
Sato, Susumu,Matsuda, Isamu,Izumi, Yusuke
, p. 5517 - 5520 (2007/10/02)
Crossed aldol reaction of trimethylsilyl enol ether with aldehyde is successfully performed with the aid of catalytic amount of rhodium complex, +X- (X = PF6 and ClO4) or Rh4(CO)12, under neutral conditions.
AN EFFICIENT METHOD FOR THE PREPARATION OF THREO CROSS-ALDOLS FROM SILYL ENOL ETHERS AND ALDEHYDES USING TRITYL PERCHLORATE AS A CATALYST
Mukaiyama, Teruaki,Kobayashi, Shu,Murakami, Masahiro
, p. 447 - 450 (2007/10/02)
Threo cross-aldol products are predominantly formed in good yields by treating tert-butyldimethylsilyl enol ethers with aldehydes in the presence of a catalytic amount of trityl perchlorate.
