Interfacial Photoelectrochemistry in Organic Synthesis

Angewandte Chemie International Edition, Accepted Article.
Photoelectrodes have traditionally enjoyed widespread attention as heterogeneous catalysts for the activation of water and CO2 in energy research, while photoelectrochemistry with homogeneous molecular catalysts dominates the activations of more complex molecules in organic synthesis.

The Chemistry and Biology of the Tetrodotoxin Natural Product Family

Angewandte Chemie International Edition, Accepted Article.
Tetrodotoxin is a neurotoxic marine alkaloid, first isolated in 1909 from pufferfish and named after the biological order tetraodontiformes. Since its structural elucidation in 1964, it has attracted the interest of synthetic organic chemists due to its exceptional polarity, complex architecture, and important biological activity.

Is Phenylnitrene a Missing Link in the Formation of Polycyclic Aromatic Nitrogen Heterocycles?

Angewandte Chemie International Edition, EarlyView.
A new formation pathway for polycyclic aromatic nitrogen heterocycles (PANHs) has been found. The reaction of phenylnitrene and the propargyl radical leads to quinoline, proving that nitrenes are suitable precursors for nitrogen incorporation mechanisms.

Total Synthesis and Structural Revision of (‐)‐Sodagnitin E

Angewandte Chemie International Edition, Accepted Article.
We report the total synthesis of malabaricane triterpene sodagnitin E, marking the first synthesis of any malabaricane natural product to date. The enantioselective synthesis of two key fragments, followed by their coupling via a Mukaiyama aldol reaction delivered the triterpene framework in a convergent synthesis.
