Remarkable enhancement of reactivity by Bronsted acids in aldol reactions mediated by Lewis acid-surfactant-combined catalysts in water
Manabe, Kei,Kobayashi, Shu
, p. 3773 - 3776 (1999)
Remarkable enhancement of reactivity by a Bronsted acid such as HCl was observed in aldol reactions of aldehydes with silyl enolates in the presence of a Lewis acid-surfactant-combined catalyst, scandium tris(dodecyl sulfate) or scandium trisdodecanesulfo
Bismuth triflate catalyzed Mukaiyama aldol reaction in an ionic liquid
Ollevier, Thierry,Desyroy, Valerie,Debailleul, Blandine,Vaur, Sophie
, p. 4971 - 4973 (2007/10/03)
We have developed an efficient, bismuth triflate catalyzed Mukaiyama aldol reaction. The reaction proceeds rapidly and affords the corresponding β-hydroxy carbonyl compound in moderate to very good yields (up to 92%). Wiley-VCH Verlag GmbH & Co. KGaA, 200
Lewis Acid Catalysis in Supercritical Carbon Dioxide. Use of Poly(ethylene glycol) Derivatives and Perfluoroalkylbenzenes As Surfactant Molecules Which Enable Efficient Catalysis in ScCO2
Komoto, Ichiro,Kobayashi, Shu
, p. 680 - 688 (2007/10/03)
Lewis acid catalysis in supercritical carbon dioxide (CO2) was investigated. While solubility of most organic materials is low in scCO 2, poly(ethylene glycol) derivatives or perfluoroalkylbenzenes were found to work as surfactants to dissolve organic materials in scCO2. In the presence of these molecules, Lewis acid catalyzed organic reactions such as aldol-, Mannich-, and Friedel-Crafts-type reactions proceeded smoothly in scCO2. Formation of emulsions was observed in these reactions, and the systems were studied in detail.
Catalytic asymmetric aldol-type reaction using a chiral tin(II) Lewis acid
Kobayashi,Uchiro,Shiina,Mukaiyama
, p. 1761 - 1772 (2007/10/02)
Highly diastereo- and enantioselective aldol-type reactions of a silyl enol ether with aldehydes including aromatic, aliphatic, and α,β-unsaturated ones are performed in propionitrile (solvent) by the use of a catalytic amount of chiral tin(II) Lewis acid
Lanthanide trifluoromethanesulfonates as reusable catalysts: Aldol reactions in organic solvents
Kobayashi,Hachiya,Takahori
, p. 371 - 373 (2007/10/02)
The aldol reaction of silyl enolates with aldehydes or acetals using a lanthanide trifluoromethanesulfonate as catalyst smoothly proceed in organic solvents to afford the corresponding aldol-type adducts in high yields. The catalyst can be easily recovere
Catalytic Asymmetric Aldol Reaction of Silyl Enol Ethers with Aldehydes by the Use of Chiral Diamine Coordinated Tin(II) Triflate
Mukaiyama, Teruaki,Kobayashi, Shu,Uchiro, Hiromi,Shiina, Isamu
, p. 129 - 132 (2007/10/02)
Highly enantioselective aldol reaction of silyl enol Ethers with aldehydes is performed by the use of a catalytic amount of chiral diamine coordinated tin(II) triflate according to a slow addition procedure.
