Collection: Chiral Building Blocks

Chiral Building Blocks — collects chiral building blocks, both heterocyclic and non-heterocyclic, together with privileged ligands and metal complexes for asymmetric hydrogenation. This category provides enantiopure fragments that serve as starting points for the synthesis of compounds with controlled stereochemistry.

Chiral Building Blocks are used by synthetic chemists to assemble target molecules with specific stereogenic centers, for example in the synthesis of active pharmaceutical ingredients and agrochemicals via stereoselective routes. Ligands and metal complexes in this category also play a role in asymmetric hydrogenation and other chiral catalysis reactions to produce products with high enantiomeric purity.

Examples of products in this collection: TCI V0077 4276-09-9 D-Valinol, TCI B5538 1013028-26-6 3-tert-Butyl 4-Methyl (4R,5S)-2,2,5-Trimethyloxazolidine-3,4-dicarboxylate, TCI V0072 1196-01-6 (-)-Verbenone, TCI B5647 146504-07-6 (1R,2R)-N1-(tert-Butoxycarbonyl)-1,2-cyclohexanediamine, TCI V0058 2026-48-4 L-Valinol, TCI B5648 180683-64-1 (1S,2S)-N1-(tert-Butoxycarbonyl)-1,2-cyclohexanediamine, TCI T4385 111769-26-7 (R)-Tetrahydrofuran-3-amine, TCI B5657 108149-65-1 tert-Butyl (S)-4-(Hydroxymethyl)-2,2-dimethyloxazolidine-3-carboxylate.

Pay attention to the stereochemical configuration (R/S) and enantiomeric purity (ee), as selecting the wrong isomer directly affects the final result of asymmetric synthesis. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.

Other categories at the same level under Asymmetric Synthesis, often used together in a single laboratory workflow:

• Chiral Catalysts, Chiral Ligands, Chiral Reagents
• Chiral Resolution Reagents
• Chiral Resolving Reagents
• Chiral Auxiliaries
• Proline-Based Organocatalysts [Asymmetric Synthesis]
• Epoxidation [Asymmetric Synthesis]

This collection is further divided into 4 more specific groups:

• Chiral Non-Heterocyclic Building Blocks
• Chiral Heterocyclic Building Blocks
• Privileged Ligands and Complexes [Asymmetric Synthesis]
• Hydrogenation [Asymmetric Synthesis]
