This review covers diastereo-and enantiodivergent catalyzed reactions in acyclic and cyclic
systems using metal complexes or organocatalysts. Among them, nucleophilic addition to …

This review highlights a number of additives that can be used to make asymmetric reactions
perfect. Without changing other reaction conditions, simply adding additives can lead to …

In the past decades there has been a dramatic increase in the demand for enantiopure
compounds for fine-chemicals (ie, agrochemicals and pharmaceuticals) and material …

Asymmetric catalysis with chiral metal complexes has received considerable attention in
recent years, and its contribution to the art of organic synthesis has become of leading …

Twenty-three diarylcarbenium ions and 38 π-systems (arenes, alkenes, allyl silanes and
stannanes, silyl enol ethers, silyl ketene acetals, and enamines) have been defined as basis …

The ion-pair concept1-4 was introduced in 1926 by Bjerrum5 to account for the behavior of
ionophores (species, such as alkali halides, that are ionic in the crystalline state and exist as …

The first enantioselective organocatalytic Mukaiyama− Michael reaction using α, β-
unsaturated aldehydes has been accomplished. The use of iminium catalysis has provided …

Direct catalytic enantio-and diastereoselective Michael addition reactions of unmodified
aldehydes to nitro olefins using (S)-2-(morpholinomethyl) pyrrolidine as a catalyst are …

Because the backbone of most of organic compounds is a carbon chain, carbon—carbon
bond-forming reactions are among the most important reactions in organic synthesis. Many …

The conjugate addition reaction of carbon nucleophiles to electron-deficient olefins is one of
the most reliable methods for selective C–C bond formation. However, the conjugate …
