Synthesis of α‐Pentafluorosulfanylated‐β2,3‐Amino Esters

open access: yesChemistryEurope, EarlyView.
De novo α‐SF5‐β2,3‐amino esters are now accessible through a straightforward aza‐Michael reaction using a series of newly developed (E)‐α‐SF5‐α,β‐unsaturated esters. Two new, highly functionalized, contiguous tertiary stereocenters are formed with diastereodivergence governed by the choice of solvent and/or base.

Synthesis and Application of Bioactive N‐Functionalized Aziridines

open access: yesAngewandte Chemie, Volume 137, Issue 44, October 27, 2025.
This review discusses modern synthetic methods for the preparation of aziridine‐containing small molecules, including biocatalytic, electrocatalytic, and photocatalytic strategies. We highlight the compatibility of various synthetic methods with control of the exocyclic N‐substituent.

Multicomponent synthesis, biological evaluation and molecular docking of new spiro-oxindole derivatives

open access: yesJournal of Taibah University for Science, 2017
A new series of spiro-oxindoles that were identified based upon their ability to inhibit methionine tRNA synthase (PDB ID: 1PFV) and glucosamine-6-phosphate synthase (PDB ID: 1JXA) enzymes in virtual screening was synthesized by a three-component 1,3 ...

Impact of polymer aging on main‐chain poly(fullerene)s with halide chain‐ends for inverted perovskite solar cells

open access: yesPolymer International, EarlyView.
Subtle variations in halogen chemistry significantly affect the aging behavior of polymeric electron transport layers in inverted perovskite solar cells, underscoring the importance of precise chemical design for enhancing long‐term stability. Abstract As perovskite solar cells (PSCs) advance toward commercialization, the need for stable and easily ...
