A Novel Merocyanine Derivative for Probing Polarity at Cubosome Interfaces

open access: yesAsian Journal of Organic Chemistry, EarlyView.
This study develops a synthetic route to C10SP, a polarity‐sensitive sensor embedded in phytantriol‐based cubosomes. Strategic steps included tertiary amine‐mediated amidation to covalently attach a hydrophobic tail and controlled nitrogen methylation to form the iminium moiety within the indolenine scaffold.

Enaminone‐Based Push–Pull Chromophores: Synthesis, Optical Properties, and Computational Insights

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Enaminones, known for their pharmacophoric properties, were combined with alkyne units to create complex chromophore structures through click‐type [2 + 2] cycloaddition‐retroelectrocyclization reactions. The ICT characteristics of the synthesized compounds were analyzed using both experimental and computational approaches.

Palladium Nanoparticles Dispersed in Alginate Beads as an Efficient, Eco‐friendly, and Sustainable Heteregeneous Catalyst: Testing in Carbon‐Sulfur and Carbon‐Carbon Cross‐Coupling Reactions

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Abstract The development of sustainable and efficient catalysts featuring palladium nanoparticles (Pd NPs) is highly sought after. In this context, sodium alginate, a natural polymer, presents a promising eco‐friendly support material for Pd NPs.

Dinitrogen Activation with Low‐Valent Strontium

open access: yesAngewandte Chemie, EarlyView.
Although computationally predicted, N2 activation with an in situ generated low‐valent β‐diketiminate (BDI) SrI precursor did not result in a stable complex. First dinitrogen fixation with Sr was achieved using a heterobimetallic approach. This highly reducing product vigorously reacts with Teflon.

Synthesis of Benzodithieno[5.5.5.6]Fenestranes: Unexpected Epimerization and Regiochemical Outcomes

open access: yesAsian Journal of Organic Chemistry, EarlyView.
Isomeric [5.5.5.6]fenestranes annulated with one benzene and two thiophene rings are accessible via di‐2‐ and di‐3‐thienylspirane intermediates. The key double cyclization step involves surprising stereoselectivity and regioselectivity. In particular, cis‐di(2‐thienyl)spirane precursors lead to the all‐cis‐fenestrane skeleton by an unexpected acid ...
