Reusable Selenenyl Iodide‐Initiated Cascade Cyclization of Polyenes with N‐terminating Groups

Chemistry – An Asian Journal, EarlyView.
A cascade cyclization of polyenes with N‑terminating groups, initiated by an isolable selenenyl iodide, was developed. The cavity‑shaped substituent stabilized both the selenenyl iodide and the selenenic acid generated via β‑selenoxide elimination, enabling the regeneration of selenenyl iodide.

Designing Enzymatic Reactivity with an Expanded Palette

ChemBioChem, EarlyView.
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...

Proline amide catalyzes formation of toxic crotonaldehyde from acetaldehyde under physiologically relevant conditions

ChemBioChem, Accepted Article.
Crotonaldehyde is a human toxin that reacts with nucleophilic groups on DNA and proteins. Putative crotonaldehyde‐derived adducts on DNA are reported in cells and patients after ethanol exposure, which implies that crotonaldehyde is formed in cells. Here, we show that proline amide, which is a model of N‐terminal proline‐containing proteins, catalyzes ...
