One-Pot Catalysis Using a Chiral Iridium Complex/Brønsted Base: Catalytic Asymmetric Synthesis of Catalponol.

Suzuki T1, Ismiyarto1, Ishizaka Y1, Zhou DY1, Asano K1, Sasai H1.
Organic letters.Org Lett.2015 Oct 23. [Epub ahead of print]
Tandem asymmetric hydrogen transfer oxidation/aldol condensation under relay catalysis of a chiral iridium complex/achiral Brønsted base binary system is described for the synthesis of α-benzylidene-γ-hydroxytetralones with high ee's. A two-step synthesis of catalponol was achieved using this seq

Organocatalyzed Multicomponent Synthesis of Isoxazolidin-5-ones.

Berini C1, Sebban M1, Oulyadi H1, Sanselme M2, Levacher V1, Brière JF1.
Organic letters.Org Lett.2015 Oct 21. [Epub ahead of print]
An unprecedented multicomponent organocatalyzed Knoevenagel-aza-Michael-cyclocondensation reaction between Meldrum's acid, hydroxylamines, and aldehydes afforded a straightforward entry to a large array of racemic and syn-diastereoenriched isoxazolidinones as synthetically useful scaffolds. This pro

An Additional Role for the Brønsted Acid-base Catalysts of Mandelate Racemase in Transition State Stabilization.

Nagar M, Bearne SL.
Biochemistry.Biochemistry.2015 Oct 19. [Epub ahead of print]
Mandelate racemase (MR) catalyzes the interconversion of the enantiomers of mandelate and serves as a paradigm for understanding the enzyme-catalyzed abstraction of an α-proton from a carbon acid substrate with a high pKa. The enzyme utilizes a two-base mechanism with Lys 166 and His 297 acting as

Axially Chiral Guanidines as Efficient Bronsted Base Catalysts for Enantioselective Transformations

Terada Masahiro
有機合成化学協会誌 68(11), 1159-1168, 2010-11-01
… In addition, the N-H proton would function as a Brønsted acidic site and hence could convey the acid/base dual function even to monofunctional guanidine catalysts. … From these basic ideas, we aimed to develop novel axially chiral guanidines as enantioselective Brønsted base catalysts. …
