Crystal structure of (2R*,3aR*)-2-phenylsulfonyl-2,3,3a,4,5,6-hexahydropyrrolo[1,2-b]isoxazole

open access: yesActa Crystallographica Section E: Crystallographic Communications, 2017
The title compound, C12H15NO3S, was prepared by 1,3-dipolar cycloaddition of 3,4-dihydro-2H-pyrrole 1-oxide and phenyl vinyl sulfone. In the molecule, both fused five-membered rings display a twisted conformation.

Synthesis of New Active Sulfones in the 5-Nitroimidazole Series

open access: yesMolecules, 2002
We describe here the preparation of new 5-nitroimidazoles which are known to have an efficacy against metronidazole-susceptible and -resistant Giarda, Trichomonas, and Entamoeba spp. The multi-step synthesis uses electron transfer methodology.

Inert Catalytic Sites Unlocked by Micropollutants for Rapid Water Decontamination with Near‐Complete Chemical Utilization

open access: yesAdvanced Materials, EarlyView.
Micropollutants can act as molecular triggers that activate a newly designed and chemically inert Fenton‐like PKU‐24 catalyst for on‐demand singlet oxygen generation from peroxymonosulfate (PMS), enabling nearly complete peroxide utilization and selective micropollutant removal from complex real‐world wastewater.

Donor–Acceptor Pentacene Analogues With Near‐Infrared Emission and Tunable Aromaticity

open access: yesAngewandte Chemie, EarlyView.
Air‐ and photostable heterocyclic pentacene analogues with donor and acceptor groups flanking a para‐quinodimethane core exhibit large dipole moments, narrow bandgaps, reversible redox behavior, and NIR‐I to NIR‐II absorption and emission with pronounced solvatochromism.

Combating the Stigmatization of Leprosy: How the first decade of The Star’s publication made the case for romantic relationships and the preservation of domestic life in the Carville Leprosarium [PDF]

open access: yes, 2013
The stigmatization of leprosy has long been acknowledged as one of the primary obstacles to not only effectively treating leprous patients on a physical level, but also achieving their integration and acceptance into society.
