, p. 550 - 553 (2008/02/06)
A catalytic asymmetric aldol reaction of alkenyl trichloroacetates with aldehydes was achieved using dibutyltin dimethoxide and BINAP · silver(I) complex as catalysts in a mixed solvent consisting of THF and MeOH. Various optically active β-hydroxy ketone
Enantioselective direct aldol-tishchenko reaction: Access to chiral stereopentads

, p. 4499 - 4501 (2007/10/03)
(Chemical Equation Presented) The aldol-Tishchenko reaction of aromatic aldehydes in the presence of titanium(IV) tertbutoxide and amino alcohols is described. When used with cinchona alkaloids, stereopentads were isolated for the first time with a high d
Chiral Lewis acid catalysis in aqueous media. Catalytic asymmetric aldol reactions of silyl enol ethers with aldehydes in a protic solvent including water

, p. 71 - 72 (2007/10/03)
Chiral copper(II)-catalyzed asymmetric aldol reactions of silyl enol ethers with aldehydes have been successfully carried out in a water-ethanol solution. The use of the protic solvent including water is essential in these reactions, and this report has proposed and demonstrated a new concept for solvents in catalytic asymmetric aldol reactions.

, p. 1381 - 1390 (2007/10/02)
A highly diastereoselective cross aldol reaction is developed using divalent tin enolates formed from stannous trifluoromethanesulfonate and carbonyl compounds.The reaction is extended to a highly enantioselective cross aldol reaction employing chiral dia
