Total Synthesis of (-)-Piericone D

Area of Science:

• Organic Chemistry
• Medicinal Chemistry
• Natural Product Synthesis

Background:

• (-)-Piericone D is a dihydrochalcone with potential antithrombotic activity.
• Its complex structure, featuring a [3.3.0] octane core, presents a synthetic challenge.

Purpose of the Study:

• To report the first total synthesis of (-)-piericone D.
• To develop a convergent synthetic route amenable to structure-activity relationship (SAR) studies.

Main Methods:

• Stereoselective β-O-glycosylation to attach the asebogenin aglycone.
• Late-stage global deprotection and simultaneous lactonization.
• Convergent synthetic strategy.

Main Results:

• Successful total synthesis of (-)-piericone D.
• Demonstration of key stereoselective and late-stage transformations.
• Establishment of a viable route for SAR investigations.

Conclusions:

• The total synthesis of (-)-piericone D was successfully accomplished.
• The developed synthetic strategy provides access to (-)-piericone D for further biological evaluation.
• This work facilitates future SAR studies to optimize antithrombotic potential.
