High‐Tg Polythioesters From Isomerization Ring‐Opening Polymerization of a Renewable Oxanorbornane‐Fused Thionolactone

Angewandte Chemie, EarlyView.
A biobased tricyclic thionolactone undergoes selective isomerization ring‐opening polymerization to yield a high‐molecular‐weight polythioester with an exceptionally high Tg of 171°C, exceeding that of the analogous polyester. The polythioester efficiently depolymerizes through backbiting, while its hydrolysis and methanolysis reveal the critical ...

Cobalt‐Catalyzed [2σ+2π] Cycloaddition via Site‐Selective Capture of Bicyclobutane Diradical

Angewandte Chemie, EarlyView.
We report a Co(II)‐catalyzed strategy that combines thermal activation of bicyclo[1.1.0]butane (BCBs) with site‐selective radical capture to furnish head‐to‐head fused bicyclo[2.1.1]hexanes via [2σ+2π] cycloaddition with indoles. Detailed mechanistic studies (31P NMR, EPR, CV, and DFT) support the catalytic pathway, while phosphine‐oxide trapping and X‐

Gain‐of‐Function Engineering of the NifEN Scaffold Into a Self‐Assembling Nitrogenase

Angewandte Chemie, EarlyView.
From scaffold to enzyme: Systematic engineering of the cofactor maturation scaffold NifEN reconstructs the P→M electron relay along with cofactor coordination and proton gating at the S2B site, converting NifEN into a functional nitrogenase capable of ATP‐dependent N2 reduction both in vitro and in vivo.
