Chiral 2,2'-bis(diphenylphosphino)-1,1'-binapthyl (Binap) ligand consists of a pair of 2-diphenylphosphinonaphthyl groups connected at the 1 and 1' positions, being of the nature of the C 2-axial chirality with optical activity of ±234°. The Binap can coordinate with many transitional metals to form stable chelation complexes, effecting the chirality transfer to the metal center for function in asymmetrically catalytic reactions. This contribution is focused on the Binap-Ru(II) catalytic system that covers the various substrates, reaction conditions, enantioselectivity of the products, reaction mechanism, and others on the basis of the prepared stable Binap-Ru(II) complexes as the clue in the text. This study will give a deep understanding of this system especially concerning the applied catalytic synthesis of the useful organic molecules.

This review introduces recent progress related to carbohydrate–metal interactions and carbohydrate‐based metal complexes. Carbohydrates are ubiquitous natural resources with highly diverse and ordered structures that serve as valuable material pools for life science and fine chemicals. In this context, efficient methods for degradation and molecular transformations of natural polysaccharides into useful compounds promoted by metal–carbohydrate interactions have been investigated. Carbohydrate‐bearing metal complexes exhibit several benefits including targeting to specific cells, enhanced cellular uptake, water solubility, and chirality. Such properties of carbohydrate–metal complexes are utilized in chemotherapy, imaging, catalysis, and other material sciences. Platinum and other metal complexes with carbohydrate ligands as anticancer agents, carbohydrate‐based drug candidates against Alzheimer's diseases, and photosensitizers are possible medicinal applications. Fluorescence, magnetic resonance, and radioactivity of carbohydrate‐based metal complexes are frequently used modalities for molecular imaging. In addition, many carbohydrate–metal complexes are used as catalysts in asymmetric synthesis. These attractive properties of carbohydrate–metal interactions and carbohydrate‐conjugated metal complexes will provide new frontiers in material and life sciences in the future.

Transition Metal Complexes with Amino Acids, Peptides and Carbohydrates in Catalytic Asymmetric Synthesis: A Short Review

The present review is devoted to the application of transition metal complexes with such ligands as amino acids, peptides and carbohydrates in catalysis. The literature published over the past 20 years is surveyed. Among the distinctive features of these ligands are their versatility, optical activity, stability and availability. Furthermore, depending on the specific synthetic task to be solved, these ligands open up almost infinite opportunity for modification. Largely thanks to their multifaceted reactivity, transition metal complexes with amino acids, peptides and carbohydrates can catalyze most of the known chemical reactions affording optically pure compounds. In this review, the emphasis is placed upon C(sp3)–H activation, cross-coupling and hydrogenation (including traditional hydrogenation in the presence of hydrogen gas and hydrogenation with hydrogen transfer) reactions. The choice is not accidental, since these reactions on the one hand display the catalytic versatility of the above complexes, and on the other hand, they are widely employed in industry.
