Synthesis of 1,3‑dicarbonyl compounds bearing hetero-substituted α-quaternary carbon via Fe(II)-catalyzed alkylation with alkylsilyl peroxides

A novel approach for the construction of α-quaternary carbon centers by an Fe(II)-catalyzed alkylation of α-alkoxy-1,3‑dicarbonyl compounds with various alkylsilyl peroxides has been developed. This strategy accommodates a broad substrate scope of 1,3‑dicarbonyl derivatives and alkylsilyl peroxides via a radical-promoted reaction pathway.
