Entry into C1 Hydroxylated Discorhabdins

Area of Science:

• Marine natural products chemistry
• Organic synthesis
• Medicinal chemistry

Background:

• Discorhabdins are marine natural products with potential as hypoxia-inducible factor 1 (HIF-1) inhibitors.
• The most potent discorhabdins feature C1 hydroxylation, a key functional group not yet achieved through synthesis.

Purpose of the Study:

• To develop a facile and stereoselective method for installing the C1 alcohol functionality onto the discorhabdin framework.
• To synthesize 14-bromo-1-hydroxydiscorhabdin V, demonstrating the utility of the new method.

Main Methods:

• Stereoselective synthesis of discorhabdins.
• Installation of C1 hydroxylation on the discorhabdin core structure.

Main Results:

• Successful and stereoselective installation of the C1 alcohol functionality on a discorhabdin analog.
• Synthesis of 14-bromo-1-hydroxydiscorhabdin V.
• This work represents the first reported C1 alcohol installation on the discorhabdin scaffold.

Conclusions:

• The developed synthetic strategy provides unprecedented access to hydroxylated discorhabdins.
• This advancement opens avenues for exploring novel discorhabdin analogs with potential therapeutic properties, particularly as HIF-1 inhibitors.
