Glycosylation via Transition-Metal Catalysis: Challenges and Opportunities
Development of efficient, mild, and easily operable stereoselective glycosylations is of critical importance to access sufficient amounts of pure and structurally well-defined carbohydrates for studies of their biological functions. Such studies will facilitate our understanding of the role of complex oligosaccharides and glycoconjugates in biological processes as well as the development of carbohydrate-based effective therapeutic agents. This review highlights recent advances in the transition metal catalyzed stereoselective glycosylations for the synthesis of a variety of structurally complex and biologically significant O-, N-, C-, and S-glycosides.

Dimeric Pyranonaphthoquinones: Isolation, Bioactivity, and Synthetic Approaches
The dimeric pyranonaphthoquinones, “bis versions” of the naphtho[2,3-c]pyran-5,10-dione moiety, comprises a group of antibiotics that have been isolated from a variety of sources including plants, bacteria, fungi, and insects. This review discusses the naturally occurring dimeric pyranonaphthoquinones, their isolation and bioactivity, and synthetic approaches toward them.

Enantioselective Catalysis by Chiral Isothioureas
Molecular Swiss Army Knives! This review covers the reactivity of chiral isothioureas, which emerged as nucleophilic organocatalysts in 2006. Multiple modes of activation rapidly came to be displayed by these heterocycles; this now makes them powerful catalysts in the toolbox of the organic chemist.

Shibasaki catalysts are a unique, highly efficient, and broadly applicable class of catalysts for use in asymmetric synthesis. It is these catalytic properties that make them attractive for industrial applications, and companies such as Actelion Pharmaceuticals, Nissan Chemicals, Hokko Chemicals, SKW Trostberg, and Sumitomo Dainippon Pharma jointly with Sunovion Pharmaceuticals have been involved in activities for their commercial use.

Cross Dehydrogenative Coupling (CDC) Reactions of N,N-Disubstituted Formamides, Benzaldehydes and Cycloalkanes
Cross dehydrogenative coupling reactions for carbon–carbon and carbon-heteroatom bond formation have experienced significant progress with substrates such as formamides, benzaldehydes and cycloalkanes. This microreview summarizes such bond formation reactions in substrates that variously are not arylated (e.g., DMF), do not contain a heteroatom (benzaldehydes) or both (cycloalkanes).

Thiamine-Diphosphate-Dependent Enzymes as Catalytic Tools for the Asymmetric Benzoin-Type Reaction
Thiamine-diphosphate-dependent (ThDP-dependent) enzymes are very efficient catalysts for asymmetric benzoin-type condensation. Through chemo- and stereoselective coupling of various carbonyl reagents promoted by enzymes of this family a wide variety of optically active α-hydroxy ketones have been produced. An overview of these synthetically relevant enzymatic benzoin-type reactions is given.

Catalytic Efficiency of Primary β-Amino Alcohols and Their Derivatives in Organocatalysis
This review demonstrates the catalytic efficiency of primary β-amino alcohols and their derivatives in organocatalysis. These simple amino alcohols are inexpensive alternatives to other primary amino organocatalysts, being easy to synthesize and air-stable and offering the potential for introduction of different functional groups and alteration of steric sites.
