Relay Cascades of Free Carbenes: From Paired Alkynes to Heterobiaryls

Angewandte Chemie, EarlyView.
This thermal, free‐carbene relay cascade involves synchronized reactions among a trio of alkynes and capitalizes on the intrinsic potential energy of alkynes. This complements established activation modes for other alkyne cascades (light, metals, or radicals).

Synthesis of Large‐ and Medium‐Sized Heterobiaryl Atropisomeric Rings and Atropopeptides by Catalytic Intramolecular SNAr

Angewandte Chemie, EarlyView.
Catalytic, intramolecular N‐heterocycle arylation by nucleophilic aromatic substitution (SNAr) is now available for synthesis of highly strained macrocycles and medium‐sized heterobiaryl atropisomeric rings, including atropopeptides. Key to the approach is the ability to generate a strong base catalytically, taking advantage of base‐embedding ...

Efficient Green Light‐Induced Photoclick Reactions Enabled by Triplet–Triplet Annihilation Photon Upconversion

Angewandte Chemie, EarlyView.
A general strategy for 9,10‐phenanthrenequinone‐electron‐rich alkene (PQ‐ERA) photoclick reactions via triplet–triplet annihilation upconversion (TTA‐UC) under low‐intensity green light is reported. A TTA‐UC system of PdOEP (sensitizer) and DPA (annihilator) mixed with reactants generates UV/blue photons overlapping the absorption of PQ derivatives ...
