TL;DR: An unusually large positive nonlinear effect was observed in these reactions, and implications of the association and self-association of NOBIN for the observed sense of asymmetric induction and nonlinear effects are discussed.
Journal ArticleDOI
Asymmetric PTC C-alkylation catalyzed by chiral derivatives of tartaric acid and aminophenols. Synthesis of (R)- and (S)-alpha-methyl amino acids

TL;DR: A new type of efficient chiral catalyst has been elaborated for asymmetric C-alkylation of CH acids under PTC conditions and a mechanism rationalizing the observed features of the reaction has been suggested.
Book ChapterDOI
Novel Types of Chiral Catalysts for Asymmetric C-C Bond Formation Reactions
TL;DR: In this article, two new chiral catalytic systems for promoting two important asymmetric organic reactions of C-C bond formation are described. But the development of asymmetric catalytic reactions is a major challenge and a subject of intense activities of the chemical community.
