A modular synthesis of functionalised phenols enabled by controlled boron speciation

Area of Science:

• Organic Chemistry
• Synthetic Chemistry
• Medicinal Chemistry

Background:

• Biaryl phenols are important structural motifs in pharmaceuticals and organic electronics.
• Existing synthetic methods for biaryl phenols can be complex and lack modularity.

Purpose of the Study:

• To develop a modular and efficient one-pot synthesis of functionalised biaryl phenols.
• To demonstrate the broad applicability of the developed method.

Main Methods:

• One-pot Suzuki-Miyaura cross-coupling of boronic acid derivatives.
• Chemoselective control of boron solution speciation to generate a reactive boronic ester in situ.
• Oxidation of the coupled products.

Main Results:

• A modular synthetic route to functionalised biaryl phenols was successfully established.
• The method demonstrated utility in synthesizing drug molecules and organic electronic components.
• The approach was also effective in iterative cross-coupling reactions.

Conclusions:

• The developed one-pot method offers an efficient and modular approach to biaryl phenol synthesis.
• This methodology has significant potential for applications in drug discovery and materials science.
• The in situ generation of reactive boronic esters enhances synthetic efficiency.
