Rapid heteroatom transfer to arylmetals utilizing multifunctional reagent scaffolds

Area of Science:

• Organic Chemistry
• Synthetic Methodology

Background:

• Arylmetals are versatile nucleophiles for C-C bond formation.
• Direct introduction of amino (-NH2) and hydroxyl (-OH) groups to arylmetals is challenging.
• Existing methods often lack scalability and environmental friendliness.

Purpose of the Study:

• To develop efficient, scalable, and environmentally friendly reagents for direct amination and hydroxylation of arylmetals.
• To utilize readily available terpenoid-derived oxaziridines as novel heteroatom-transfer reagents.
• To provide a simplified synthetic route to primary anilines and phenols.

Main Methods:

• Employing bench-stable N-H and N-alkyl oxaziridines derived from terpenoids.
• Reacting these oxaziridines with diverse aryl- and heteroarylmetals.
• Conducting reactions at low temperatures without transition-metal catalysts or protecting groups.

Main Results:

• Successful direct primary amination and hydroxylation of various aryl- and heteroarylmetals.
• One-step synthesis of primary anilines and phenols.
• Demonstrated scalability and mild reaction conditions.

Conclusions:

• Terpenoid-derived oxaziridines are effective multifunctional reagents for arylmetal functionalization.
• This method offers a practical, green, and efficient alternative for synthesizing anilines and phenols.
• The approach bypasses the need for transition metals, ligands, and protecting groups, simplifying synthetic procedures.
