The Synthesis Use of a Difluorinated Amino‐Benzo‐Cinnoline Dyes (ABCDyes) Enables Fine Tuning of Emission Through Double SNAr Late‐Stage Functionalization

European Journal of Organic Chemistry, Volume 29, Issue 29, 7 August 2026.
An efficient synthesis of difluorinated amino‐benzo‐cinnoline dyes (ABCDyes) is reported. Their use for the late‐stage introduction of internal dinucleophilic species through a double SNAr reaction enables straightforward access to previously unexplored ABCDye analogs displaying tunable emission ranging from green to red.

Chemoenzymatic Synthesis of Chiral Piperidines Using the Immobilized Transaminase ATA‐117 in Continuous Flow Reactors

Advanced Synthesis &Catalysis, Volume 368, Issue 15, 1 August 2026.
A robust continuous flow chemoenzymatic process was developed for the stereoselective synthesis of cis‐(2R,6R)‐2,6‐disubstituted piperidines, including the natural alkaloid (–)‐pinidinone. The asymmetric transamination of α,β‐unsaturated ketones was catalyzed by immobilized ATA‐117, followed by spontaneous aza‐Michael cyclization, providing the desired

Photochromic carbazole photoinitiators for precision visible‐light photopolymerization

Polymer International, Volume 75, Issue 8, Page 722-728, August 2026.
New carbazole–naphthopyran derivatives were employed as visible‐light‐activated photoinitiators, enabling rapid and localized radical photopolymerization to produce well‐defined thin solid objects within minutes. Abstract Two carbazole derivatives, each incorporating a naphthopyran unit and an aromatic ketone, were synthesized and evaluated as ...

Resilience of floral scent emission after florivory

Plant Biology, Volume 28, Issue 5, Page 1491-1506, August 2026.
Florivory is thought to affect floral traits, impacting pollination. However, our data suggest a stability in post‐florivory scent emission, which may guarantee the maintenance of pollinator visitation regardless of florivory, indicating a resilience of natural systems with multiple and simultaneous interactions. Created in BioRender. Tunes, P.

The synthesis of 4H-pyran containing hemispherands via pyrylium salts [PDF]

Tetrahedron Letters, 1986
Two new hemispherands 2a and 2b containing a central 4H-pyran unit were synthesized via appropiately substituted 2,6-phenyl pyrylium salts; largest ΔGo values of complexation of 2a and 2b with different alkali picrates are found for Na+ and K+.
