Dual Photoredox/Cu‐Catalysis Enables Diastereoselective Synthesis of 3‐β‐Ethynyltropanes via Decarboxylative Alkynylation

Advanced Synthesis &Catalysis, EarlyView.
A copper‐catalyzed decarboxylative alkynylation of tropanes is developed. This approach works under mild conditions and selectively produces a range of 3‐β‐alkynylated tropanes. Moreover, it provides a versatile and convergent platform for further functionalization of the triple bond.

Impact of the Substitution Pattern in N–heterocyclic Olefin‐Substituted Phosphines on Palladium Catalysis

Advanced Synthesis &Catalysis, EarlyView.
The impact of olefin backbone substitution in N‐heterocyclic olefin‐substituted phosphines is investigated. While these ligands are highly electron‐donating, their catalytic activity in Pd‐catalyzed CN cross‐coupling reactions decreases as the size of the backbone substituent increases.

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.
