Asymmetric Synthesis

Borylation

Organoboron compounds play an important role in organic synthesis, medicinal chemistry, catalytic reactions and materials science. Their application in cross-coupling reactions provides a powerful tool for the synthesis of new organic molecules, while in drug design and materials science, the unique properties of organoboron compounds make them important molecular building blocks. With the deepening of scientific research, organoboron compounds will play an increasingly important role in more fields.

Epoxidation

Epoxidation is an important organic chemical reaction that can effectively introduce oxygen atoms into organic molecules and adjust the reactivity of molecules by converting double bonds into epoxy groups. Epoxides are important intermediates that can be further synthesized into various functionalized compounds through ring-opening reactions. Therefore, this reaction is widely used in the fields of medicinal chemistry, materials science, agricultural chemistry, etc.

Hydrogenation

Hydrogenation is a common chemical reaction that saturates organic compounds by adding hydrogen (H2) to unsaturated bonds (such as double or triple bonds). Hydrogenation is usually carried out in the presence of a catalyst, and common catalysts include platinum (Pt), palladium (Pd), nickel (Ni), etc.

Hydroxylation

Hydroxylation is a chemical reaction that refers to the process of introducing one or more hydroxyl (-OH) groups into a molecule. Typically, hydroxylation occurs on hydrocarbon groups in organic molecules (such as olefins, aromatics, or alkanes) to produce compounds containing hydroxyl groups.

MacMillan Imidazolidinone Organocatalysts

MacMillan's imidazolidinone organocatalyst is an important class of organocatalysts, which are widely used in asymmetric catalytic reactions, especially in chiral control in organic synthesis. Reaction types of MacMillan imidazolidinone catalysts: asymmetric addition reaction, asymmetric reduction reaction, cyclization reaction, etc.

Chiral Catalysts (Other)

Chiral catalysts are a class of catalysts that can introduce or control chirality (stereochemical differences) in chemical reactions. The role of chiral catalysts is to efficiently catalyze a series of stereoselective reactions to produce chiral compounds in the absence of metal catalysts. Chiral catalysts are often used in asymmetric catalytic reactions and have important applications in the fields of pharmaceuticals, fine chemical synthesis, and natural product synthesis.

Chiral Ligands (Other)

Chiral ligands refer to ligands with chiral structures, which are usually used in coordination chemistry to form complexes with metal centers. Chiral ligands have important applications in asymmetric catalysis, drug synthesis, fine chemical synthesis, etc., especially in controlling stereochemical selectivity. Chiral ligands can introduce or control the chirality of reactants in catalytic reactions through their unique stereostructures and synergistic effects with metal centers, thereby affecting the stereochemistry of the products.

Chiral Organocatalysts (Other)

Chiral organocatalysts play an indispensable role in modern organic synthesis, especially in asymmetric synthesis, where they can efficiently and selectively generate products with specific stereostructures. This catalytic method is not only efficient, environmentally friendly, and economical, but is also widely used in the fields of pharmaceuticals, pesticides, and natural product synthesis. With the deepening of research, the importance of chiral organocatalysts in chemical synthesis will continue to grow.

Phase Transfer Reaction

Phase transfer reactions are a type of reaction involving two immiscible solvent phases (usually aqueous and organic). In this reaction, certain substances are able to transfer between the two phases, allowing the reactants to pass between the two phases and undergo a chemical reaction. The key to this reaction is a phase transfer catalyst that can facilitate the transfer of reactants from one solvent phase to another.

Privileged Ligands and Complexes

Proline-Based Organocatalysts

Proline-based organocatalysts have attracted much attention in the field of organocatalysis in recent years, especially in metal-free catalytic reactions. Proline is a natural amino acid that not only has good catalytic performance, but also has a simple structure, is non-toxic, and has a wide range of sources, which conforms to the concept of green chemistry.

Reduction

Reduction reactions are widely used in chemistry and industry. They reduce substances by transferring electrons, thus reducing the oxidation state of substances. They play an important role in many fields, such as metal extraction, organic synthesis, and environmental protection.
