Formal Cyclopropylation of Imines with Cyclopropanols: Stereocontrolled Access to Conformationally Constrained γ‐Amino Alcohols

Angewandte Chemie, EarlyView.
A formal cyclopropylation of imines with cyclopropanols enables stereoselective access to cyclopropane‐embedded γ‐amino alcohols bearing three contiguous stereocenters. The transformation proceeds through a sequence of Mannich‐type addition and ring closure involving enolized zinc homoenolate, and is applicable to both N‐sulfonyl and chiral N‐sulfinyl ...

Ostwald Ripening as a Tool for Controlling Dynamic Nanomaterials

Aggregate, EarlyView.
This editorial highlights the potential of controlling Ostwald ripening, the net diffusion of material from smaller to larger particles. Ostwald ripening can occur in any dispersed system and therefore has the potential to be a powerful tool for both creating new nanomaterials and introducing mechanisms of time dependent behavior.

Mechanistic Divergence in Sulfur‐Ligated Iron(III)‐Alkylperoxo Reactivity: Aldehyde Oxidation Prevails over Deformylation

Angewandte Chemie, EarlyView.
This study explores the mechanistic investigation into an unusual reactivity of a thioether‐ligated low‐spin Fe(III)‐alkylperoxide with cyclohexane–carboxaldehyde as a mimic of nonheme iron(II) enzyme intermediates and highlights that only efficient catalysis happens from a high‐valent iron(IV)‐oxo species.

Covalent Bond Regulation in Nanographene: En Route to Precise Aggregation State Modification

Aggregate, EarlyView.
Regulation of nanographene from covalent bond to control the aggregation state of nanographene precisely was achieved by protonic acid or Lewis acid. The fused azulene unit(s) at the margin of molecules played an important role for the unique chemical activity and physical features. Furthermore, quencher and reaction temperature would lead to selective

Total Synthesis of Calyciphylline F

Angewandte Chemie, EarlyView.
The final challenge in the total synthesis of the caged polycyclic Daphniphyllum alkaloids was the Calyciphylline D‐type alkaloid, featuring a strained 8‐azatricyclo[4.2.1.04,8]nonane ring system. Presented herein is the total synthesis of calyciphylline F, a member of the calyciphylline D‐type alkaloid family, by an intramolecular [4 + 3 ...
