Recent progress on the stereoselective synthesis of cyclic quaternary α-amino acids

Abstract: The most recent papers describing the stereoselective synthesis of cyclic quaternary α-amino acids are collected in this review The diverse synthetic approaches are classified according to the size of the ring and taking into account the bond that is formed to complete the quaternary skeleton

Stereoselective synthesis of γ-amino acids

Abstract: γ-Amino acids have attracted considerable attention as biologically active compounds in the central nervous system (CNS) of mammals. Over the last few years, significant interest in the stereoselective synthesis and practical application of linear and cyclic chiral γ-amino acids in the synthesis and design of α,β- and β,γ-hybrid peptides with definite secondary structures and design of nanotubes has been reported, thus demonstrating the theoretical interest and the practical importance of γ-amino acids. An overview of synthetic approaches to linear and cyclic chiral γ-amino acids and derivatives is presented. Data on the practical applications of γ-amino acids are also discussed.

I and i

Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality. Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

Asymmetric multicomponent reactions (amcrs): the new frontier

Abstract: Asymmetric multicomponent reactions involve the preparation of chiral compounds by the reaction of three or more reagents added simultaneously. This kind of addition and reaction has some advantages over classic divergent reaction strategies, such as lower costs, time, and energy, as well as environmentally friendlier aspects. All these advantages, together with the high level of stereoselectivity attained in some of these reactions, will force chemists in industry as in academia to adopt this new strategy of synthesis, or at least to consider it as a viable option. The positive aspects as well as the drawbacks of this strategy are discussed in this Review.
