Organic Analytical Chemistry Lab
Machine-translated · View original
A lab that develops new reactions using organocatalysts and takes on the total synthesis of natural products.

AboutAbout the lab
Making molecules selectively with organocatalysts
The Hayashi Lab studies the development of new asymmetric reactions using organocatalysts and the total synthesis of biologically active natural products.
The lab also works on producing, by chemical synthesis, natural products that can be obtained from nature only in small amounts.
On the lab's website, it is presented under the name "Hayashi Lab."
Key terms
- Organocatalyst
- A catalyst that drives a reaction through the action of an organic compound itself, without using metals
- Asymmetric reaction
- A reaction that selectively produces more of one of two molecules that are mirror images of each other
- Total synthesis
- Assembling a complex molecule, such as a natural product, from simple, readily available starting materials using only chemical reactions

The Hayashi Lab works on developing new asymmetric reactions using organocatalysts and on the total synthesis of biologically active natural products. Natural products sometimes cannot be obtained from nature in sufficient quantities, and supplying them by chemical synthesis is one way to solve this problem.
*Illustrative imageDevelopment of Asymmetric Reactions Using Organocatalysts
This research uses organocatalysts to achieve catalytic asymmetric reactions, which are regarded as important in modern organic synthesis. Using readily available proline as the catalyst, the lab has discovered reactions that selectively produce one of the two mirror-image forms (enantiomers) with high selectivity.
*Illustrative imageTotal Synthesis of Natural Products
Some biologically active natural products are available from nature only in small amounts, which prevents biological research on them from moving forward. The lab pursues the total synthesis of such rare compounds, building on highly original methodology.
