Total synthesis of resolvin D3

Area of Science:

• Organic Chemistry
• Medicinal Chemistry
• Synthetic Chemistry

Background:

• Resolvins are a class of specialized pro-resolving mediators derived from omega-3 polyunsaturated fatty acids.
• These compounds play crucial roles in resolving inflammation and promoting tissue repair.
• The precise chemical synthesis of resolvins is essential for studying their biological functions and therapeutic potential.

Purpose of the Study:

• To develop a robust synthetic route for Resolvin D3.
• To establish stereogenic centers with high selectivity during synthesis.
• To provide a reliable supply of Resolvin D3 for further biological investigation.

Main Methods:

• Suzuki-Miyaura cross-coupling reaction between a C1-C8 borane and a C9-C22 iodoolefin intermediate.
• Sequential Wittig reactions to construct the carbon backbone of the iodoolefin intermediate.
• Ruthenium-catalyzed asymmetric transfer hydrogenation to establish stereogenic centers at C4, C11, and C17.

Main Results:

• Successful synthesis of Resolvin D3 was achieved.
• The key C9-C22 iodoolefin intermediate was prepared via sequential Wittig reactions.
• High stereoselectivity was obtained in the construction of stereogenic centers using asymmetric transfer hydrogenation.

Conclusions:

• A viable synthetic strategy for Resolvin D3 has been established.
• The synthetic route allows for the controlled introduction of crucial stereochemistry.
• This synthesis facilitates further research into the pharmacological properties of Resolvin D3.
