Gold(I)‐Catalyzed Domino Cyclization for the Construction of Trispirocyclic Cyclohexanes

ChemistryEurope, EarlyView.
We describe herein a series of intricate trispirocyclic architectures that have been synthesized from readily available substrates through an operationally simple one‐pot transformation under mild conditions. An unprecedented gold(I)‐catalyzed domino cyclization involving 2‐ethynylbenzyl alcohol derivatives and heterocyclic α,β‐unsaturated imines ...

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Intertwined Processes in the Pummerer‐Type Rearrangement Affording α‐Trifluoromethoxylated Thioethers and the Corresponding Highly Enantioenriched Sulfoxides

Chemistry – A European Journal, EarlyView.
Highly stereoenriched α‐trifluoromethoxylated sulfoxides were accessed from racemic aryl methyl sulfoxides, by means of a trifluoromethoxylative Pummerer rearrangement and a highly enantioselective sulfoxidation. The 2‐step procedure could be performed in one pot.
