Researchers explore switchable asymmetric catalysis using chiral organic catalysts. This approach enables the efficient production of diverse chiral products from the same starting materials by tuning catalytic conditions.
Area of Science:
- Organic Chemistry
- Asymmetric Catalysis
- Stereoselective Synthesis
Background:
- Achieving switchable chemo-, regio-, or diastereodivergent reactions is a key objective in asymmetric catalysis.
- This involves producing multiple, distinct chiral products from identical starting materials.
- Tunable catalytic conditions are essential for controlling reaction pathways.
Purpose of the Study:
- To review the application of chiral organic catalysts in switchable stereoselective reactions.
- To highlight the use of Lewis bases, Brønsted bases, and Brønsted acids.
- To discuss synergistic catalysis involving organocatalysis and metal catalysis.
Main Methods:
- Focus on chiral organic catalysts (Lewis bases, Brønsted bases, Brønsted acids).
- Examination of switchable stereoselective reactions.
- Inclusion of examples of divergent reactions via synergistic activation.
Main Results:
- Demonstration of switchable control over chemo-, regio-, and diastereoselectivity.
- Efficient synthesis of structurally and stereochemically diverse chiral products.
- Successful application of various chiral organic catalysts.
Conclusions:
- Chiral organic catalysts offer a versatile platform for switchable asymmetric catalysis.
- Tunable catalytic conditions are crucial for accessing diverse chiral outcomes.
- Synergistic approaches can further expand the scope of divergent reactions.

The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
