Modular Access to Bridgehead Heterocycle‐Substituted Bicyclo[1.1.0]butanes via Late‐Stage Functionalization of Alkynylbicyclo[1.1.0]butanes

Chemistry–Methods, Volume 6, Issue 4, April 2026.
A modular late‐stage manifold exploits the embedded alkyne of alkynylbicyclo[1.1.0]butanes (ABCBs) to deliver triazole‐, isoxazole‐, free‐NH‐pyrrole, free‐NH‐pyrazole, or silacyclohexene‐decorated BCBs in a single operation. Strain‐release transformations of bicyclo[1.1.0]butanes are powerful methods for constructing four‐membered rings and bicyclo[n.1.

Excimer Formation in Aqueous Solutions of Hosts and Application in Synthesis

ChemPhotoChem, Volume 10, Issue 4, April 2026.
This review explores how host‐mediated excimer formation in water, facilitated by supramolecular confinement enhances photochemical synthesis. By improving solubility, local concentrations, and orientational control, these systems can boost efficiency and selectivity in reactions like photocycloadditions and photodimerizations.

Amphiphilic Polymer Model Networks Synthesized by Different Hetero‐Complementary Coupling Reactions of Tetra‐PEG and Tetra‐PCL Stars

Macromolecular Chemistry and Physics, Volume 227, Issue 7, 14 April 2026.
Amphiphilic co‐networks (ACN) synthesized by different hetero‐complementary reactions of hydrophilic tetra‐PEG and hydrophobic tetra‐PCL stars are compared. For the ACNs, equilibrium volume swelling degrees (Qv) are determined. Information about the ACNs micro structure (connectivity distribution) is obtained from proton low‐resolution multiple‐quantum

Nucleophilic substitution of a phthalimidyl group with morpholine in an N1‐methyl‐1,2,3‐triazole: crystallographic evidence for migration of the methylene bridge

Acta Crystallographica Section C, Volume 82, Issue 4, Page 144-150, April 2026.
X‐ray crystallography revealed that the reaction of 2‐{[4‐(4‐bromophenyl)‐1H‐1,2,3‐triazol‐1‐yl]methyl}phthalimide with morpholine led to substitution of the phthalimide group, including migration of the substituent from N1 to N2 on the 1,2,3‐triazole ring.2‐{[4‐(4‐Bromophenyl)‐1H‐1,2,3‐triazol‐1‐yl]methyl}phthalimide, C17H11BrN4O, was synthesized by ...
