Background:

• Hyperireflexolide A is a complex natural product with potential biological significance.
• Efficient and stereoselective synthetic routes are crucial for accessing such molecules.

Purpose of the Study:

• To develop the first synthetic strategy for hyperireflexolide A.
• To establish a robust method for constructing the core structure of hyperireflexolide A.

Main Methods:

• Synthesis of a functionalized γ-lactone-fused cyclopentane intermediate (5).
• Stereoselective α-allylation and α-methylation of intermediate 5.
• Cross-metathesis reaction to form an α,β-unsaturated ketone precursor (11).

Main Results:

• Successful synthesis of key intermediate 5.
• Stereoselective introduction of substituents at C-8 and C-10.
• Formation of α,β-unsaturated ketone 11, a precursor for hyperireflexolide A.

Conclusions:

• The presented approach provides a viable first synthesis of hyperireflexolide A.
• The developed methodology enables stereoselective construction of key structural motifs.
