Journal ArticleDOI
A reversal phenomenon of enantioface selectivity by the cooperative operation of two chiral catalysts
Tsuneomi Kawasaki,Yuki Wakushima,Mai Asahina,Kazuya Shiozawa,Tomoyuki Kinoshita,François Lutz,Kenso Soai +6 more
TL;DR: The reversal phenomenon of enantioface selectivity in the asymmetric addition of diisopropylzinc to aldehydes was observed by mixing two chiral β-amino alcohol catalysts that possess individual enantioselectivity.
Journal ArticleDOI
Highly Enantioselective Addition of Dialkylzincs to Aromatic Aldehydes Using 1-Phenyl-2-(1-pyrrolidinyl)-1-propanol as a Chiral Catalyst
Journal ArticleDOI
Highly Enantioselective Asymmetric Synthesis by the Design of Asymmetric Catalysts and Reaction Media
TL;DR: In this paper, an asymmetric autocatalyst with very low (ca. 0.00005%) ee enhances its ee significantly up to > 99.5% ee in a yield of > 99% was attained using pyrimidyl alkanol as a chiral activator.
Journal ArticleDOI
Elucidation of the Structures of Asymmetric Autocatalyst Based on X-ray Crystallography
Arimasa Matsumoto,Satoshi Fujiwara,Takaaki Abe,Atsushi Hara,Takayuki Tobita,Taisuke Sasagawa,Tsuneomi Kawasaki,Kenso Soai +7 more
TL;DR: In this article, a single-crystal X-ray crystallography of the formed zinc alkoxide crystals shows the existence of tetramer or higher oligomer structures in this asymmetric autocatalytic system.
Journal ArticleDOI
The design of chiral dendritic catalysts and ligands bearing chiral sites at the periphery for the highly enantioselective addition of dialkylzincs to aldehydes and N-diphenylphosphinylimines
Kenso Soai,Itaru Sato +1 more
TL;DR: Soai et al. as discussed by the authors showed that chiral dendrimers bearing β-amino alcohols on their hyperbranched chain-ends serve as highly enantioselective catalysts and ligands in the addition of dialkylzincs to aldehydes with up to 93% ee.
