Synergistic Visible Light Nanophotocatalysis and Asymmetric Organocatalysis for the Stereoselective α‐Alkylation of Aldehydes

Advanced Synthesis &Catalysis, EarlyView.
An unprecedent dual catalytic nanophotocatalytic and asymmetric organocatalytic system for the α‐functionalization of aldehydes is developed using carbon nanodots as photosensitizers. The optimized methodology yields the alkylated products with up to 94% yield and up to 98:2 e.r., evidencing the possible recycling of the nanocatalysts.

Deazaflavin‐Catalyzed Arylation of White Phosphorus with Aryl Bromides and Chlorides

Advanced Synthesis &Catalysis, EarlyView.
The 5‐aryldeazaflavin photocatalyst o‐Me‐dFl catalyzes the arylation of white phosphorus with aryl chlorides and bromides under near UV‐LED irradiation, affording triarylphosphines and tetraarylphosphonium salts. Nuclear magnetic resonance studies and density functional theory calculations offer insights into the reaction pathway.

Three‐Component Synthesis of γ‐Amino Esters with α‐Quaternary Carbon Centers via NHC/Photoredox Dual Catalysis

Advanced Synthesis &Catalysis, EarlyView.
γ‐Amino acid derivatives with an α‐quaternary center are prevalent in medicinally important compounds. A dual N‐heterocyclic carbene/photocatalytic pathway is developed for the three‐component synthesis of α, α ‐disubstituted γ‐amino esters. This methodology allows for the rapid synthesis of diverse libraries of γ‐amino esters in good yields.
