From Alkylarenes to α-Amino Acid Derivatives via C-Difunctionalization

Area of Science:

• Organic Chemistry
• Synthetic Chemistry
• Catalysis

Background:

• Nitrogenation of carbon-carbon (C-C) bonds is crucial for incorporating nitrogen into molecules, offering step and atom economy.
• Current C-C bond nitrogenation methods are limited to C-monofunctionalization due to the difficulty of cleaving inert C-C bonds.

Purpose of the Study:

• To develop a novel C-C bond difunctionalization strategy for alkylarenes.
• To enable the synthesis of unnatural amino acids through C-C bond cleavage and amination.
• To advance C-C bond amination beyond traditional monofunctionalization.

Main Methods:

• A novel C-difunctionalization strategy involving C-C bond cleavage of alkylarenes.
• Utilizing an entropy-driven remodeling strategy for skeleton restructuring.
• Employing precisely controlled chemoselectivity for stepwise carbon editing.

Main Results:

• Successful C-difunctionalization of alkylarenes via C-C bond cleavage.
• Established a unique pathway for synthesizing unnatural amino acids.
• Demonstrated a method moving beyond C-monofunctionalization to higher-order C-multifunctionalization.

Conclusions:

• The developed C-difunctionalization strategy offers a new pathway for C-C bond amination.
• This approach enables high-value upgrading of petrochemical feedstocks and late-stage modification of complex molecules.
• The reaction provides abbreviated synthesis routes for bioactive molecules.
