Saha, Satyajit,Moorthy, Jarugu Narasimha
, p. 396 - 402 (2011/04/17)
From a systematic investigation involving the synthesis of a series of catalysts and screening studies, the organocatalyst 16, which is sterically hindered, contains a strong hydrogen-bonding site, and is endowed with reinforced chirality, is shown to pro
The mimic of type II aldolases chemistry: Asymmetric synthesis of β-Hydroxy Ketones by Direct Aldol Reaction: Research Letter
Lu, Zhijin,Mei, Haibo,Han, Jianlin,Pan, Yi
experimental part, p. 181 - 186 (2011/03/20)
An efficient direct aldol reaction has been developed for the synthesis of chiral β-hydroxy ketone using a combination of C1-symmetric chiral prolinamides based on o-phenylenediamine and zinc triflate as catalyst. The reaction was convenient to

supporting information; experimental part, p. 3177 - 3181 (2009/04/11)
An enantioselective Biginelli reaction that proceeds by a dual-activation route has been developed by using a combined catalyst of a readily available trans-4-hydroxyproline-derived secondary amine and a Bronsted acid. Aromatic, heteroaromatic, and fusedr
The Enantioselective Michael Addition of Thiols to Cycloalkenones by Using (2S,4S)-2-Anilinomethyl-1-ethyl-4-hydroxypyrrolidine as Chiral Catalyst
Suzuki, Keisuke,Ikegawa, Akihiko,Mukaiyama, Teruaki
, p. 3277 - 3282 (2007/10/02)
Catalytic asymmetric addition of thiols to 2-cycloalkenone was studied by using the chiral amino alcohols, derived from L-hydroxyproline or (S)-proline, as base catalysts.Detailed investigation was carried out on the effects of the structure of the cataly
