Rhodium-Catalyzed [5 + 1 + 2] Cycloaddition of Yne-3-Acyloxy-1,4-Enynes (YACEs) and Carbon Monoxide: Reaction Development and Mechanism

Developing new reaction to synthesize challenging eight-membered carbocycles is a research frontier of organic synthesis. Reported here is the development of the first Rh-catalyzed [5 + 1 + 2] cycloaddition of yne-3-acyloxy-1,4-enyne (Yne-ACEs, short as ...

A Chiral Saddle‐Shaped Nanographene With Two Heptagon‐Embedded [4]Helicenes

Angewandte Chemie International Edition, EarlyView.
We present a novel synthetic strategy toward a chiral saddle‐shaped nanographene (cSNG) via a two‐step oxidation of a prochiral anthracene precursor. The Scholl‐type oxidation first yields a key intermediate with sp3‐defect heptagons, and subsequent oxidative dehydrogenation affords fully conjugated cSNG.

Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, EarlyView.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.
