Chiral Materials from Biomass: 3‐deoxy‐α‐D‐ribono‐1,4‐lactone and 3‐deoxy‐α‐D‐arabino‐1,4‐lactone via the Bromination of Cyrene

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The biomass pyrolysis product levoglucosenone enables the preparation of the feeding modulator 3‐deoxy‐d‐arabino‐1,4‐lactone and the diastereomer 3‐deoxy‐d‐ribono‐1,4‐lactone. The key steps involve a diastereoselective bromination using an enamine bromination‐hydrolysis strategy on the bicyclic ring‐system followed by selective nucleophilic ...

One‐Pot Synthesis of Fluorinated Pyrimidine Derivatives from Aldehydes by Photocatalytic α‐Perfluoroalkenylation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Perfluoroalkylated pyrimidines simply made: By a combination of photocatalytic α‐alkenylation and subsequent ring closure simple aldehydes are transformed into the functionalized heterocycles. A phosphine and an imidazolidinone are both employed as catalysts in a convenient one‐pot method.

Contextualisation of salinisation and adaptation preferences in the coastal areas of Bangladesh: Bringing together farmers' salinity perspectives into place‐based policy initiatives

open access: yesLand Degradation &Development, Volume 33, Issue 18, Page 3882-3900, December 2022., 2022
Abstract The salinisation of coastal areas in Bangladesh reduces livelihood options for rice intensification but offers a more suitable environment for shrimp and salt farming. Thus, farmers' salinity perspectives might vary resulting in contested land use settings that may create uncertainties for policymakers in planning adaptation initiatives to ...

Effects of central imidazolinergic and alpha2-adrenergic activation on water intake

open access: yesBrazilian Journal of Medical and Biological Research, 2001
Non-adrenergic ligands that bind to imidazoline receptors (I-R), a selective ligand that binds to alpha2-adrenoceptors (alpha2-AR) and mixed ligands that bind to both receptors were tested for their action on water intake behavior of 24-h water-deprived ...
