We report a heterogeneous photocatalytic system for the construction of valuable γ-amino acid scaffolds through the carboxylation of alkenes with the ambient CO2. The system provides a green and sustainable methodology to the synthesis of amino acid derivatives in one-step with visible light.
Abstract
A metal-free heterogeneous protocol is established herein for the synthesis of value-added γ-amino acid scaffolds via carbocarboxylation of alkenes with CO2 and alkylamines under visible light irradiation. The protocol shows broad substrate scope under mild reaction conditions and good stability of the catalyst for recycle tests. Moreover, the methodology could be feasible to the late-stage derivatization of several natural products, enriching the chemical arsenal for practical application.
