Easy Access to γ-Iodo-gem-Diborylated-Cyclopentanes and Bicyclic Cyclopropanes [PDF]
A formal atom transfer radical [3+2] annulation (ATRAn) reaction between different homoallyl radical precursors and 1,1-diborylethene was developed. It provides a rapid access to polysubstituted cyclopentanes containing a gem-diboronic ester moiety.

3,4‐Arylvinyl Pyrrolidines and Cyclopentanes
, 2022 The cascade cyclization reactions of 1,5-bisallenes grant access to a great variety of products by precisely tuning the catalyst system and/or the reagents involved. Herein, we present our findings that 1,5-bisallenes react with two molecules of dimethyl

Molecular filming: A director's grammar for visualizing chemistry in motion
Bulletin of the Korean Chemical Society, EarlyView.Molecular filming names the practice, not just the product, of ultrafast structural science. In deliberate analogy to molecular editing, which rewrites connectivity in space, molecular filming records geometry in time, assembling time‐ordered structural frames into a movie of atomic motion and recasting the field as a grammar of directorial choices ...

Borylcyclopropanes: Synthetic Strategies and Applications
Angewandte Chemie, Volume 138, Issue 37, 7 September 2026.Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...

Chemistry – A European Journal, EarlyView.Cyclopropylamines have emerged as powerful photocatalytic building blocks. Upon light‐induced single‐electron oxidation, they undergo strain‐release ring opening to generate distonic iminium radicals that enable diverse transformations, including ring‐opening functionalization, formal [3 + 2] cycloadditions, radical cascades, and asymmetric bond ...

Chemistry – A European Journal, EarlyView.Captured in water. A tetrasulfonated deep‐cavity calix[4]arene encapsulates linear and cyclic alkanes, as well as benzene and hexafluorobenzene, in water by forming a self‐assembled dimeric capsule. The binding affinity is guest size‐dependent. For linear alkanes, the affinity peaks at n‐hexane, while cyclooctane is the most strongly bound cycloalkane.
