Total synthesis of antillatoxin

Area of Science:

• Organic Chemistry
• Synthetic Chemistry
• Natural Product Synthesis

Background:

• Antillatoxin is a natural product with potential biological activity.
• The development of efficient synthetic routes is crucial for studying and utilizing natural products.

Purpose of the Study:

• To achieve the total synthesis of natural (4R,5R)-antillatoxin.
• To synthesize its stereoisomer, (4S,5S)-antillatoxin.
• To establish a reliable method for preparing optically pure key intermediates.

Main Methods:

• Indium-mediated allylation of primary or secondary allylic bromide with aldehyde in aqueous media.
• Highly selective Luche's reduction.
• Chiral resolution techniques.

Main Results:

• Successful total synthesis of both (4R,5R)-antillatoxin and (4S,5S)-antillatoxin.
• Preparation of optically pure key intermediates via indium-mediated allylation.
• Demonstration of high selectivity in Luche's reduction.

Conclusions:

• The developed synthetic strategy is effective for accessing antillatoxin and its analogs.
• The use of indium-mediated allylation offers a green and efficient approach in aqueous media.
• This work provides access to stereochemically defined antillatoxin analogs for further investigation.
