4′-(N-(Propargyl)pyrrol-2-yl)-2,2′:6′,2′′-terpyridine
A new terpyridine molecule, bearing a N-propargylated pyrrole, was prepared and characterized. Its synthesis was based on a Krohnke-type reaction between 2-acetylpyridine and N-propargylpyrrole-2-carboxaldehyde in a basic medium. An allene-containing terpyridine was also obtained as a by-product.
Glaciological data Austre Lovén Svalbard
These data are measured in High Arctic over an observatory basin, located at 79°N on the W coast of Svalbard.

New spiropyrrolothiazole derivatives bearing an oxazolone moiety as potential antidiabetic agent: Design, synthesis, crystal structure, Hirshfeld surface analysis, ADME and molecular docking studies
In a sustained search for novel and effective antihyperglycemics, a new series of fifteen isomeric oxazolone-fused dispiropyrrolothiazoles resulting from one-pot three component reaction between L-4-thiazolidine carboxylic acid, arylidene-oxazolones and isatin (or acenaphthenequinone) has been ...
Antimicrobial Activity and DFT Studies of a Novel Set of Spiropyrrolidines Tethered with Thiochroman-4-one/Chroman-4-one Scaffolds
A novel series of 14 spiropyrrolidines bearing thiochroman-4-one/chroman-4-one, and oxindole/acenaphthylene-1,2-dione moieties were synthesized and characterized by spectroscopic techniques, as well as by three X-ray diffraction studies, corroborating the stereochemistry. Quantum chemical ...
Synthesis, antidiabetic activity and molecular docking study of rhodanine-substitued spirooxindole pyrrolidine derivatives as novel α-amylase inhibitors
In a sustained search for novel α-amylase inhibitors for the treatment of type 2 diabetes mellitus (T2DM), we report herein the synthesis of a series of nineteen novel rhodanine-fused spiro[pyrrolidine-2,3′-oxindoles]. They were obtained by one-pot three component [3 + 2] cycloaddition of stabilized ...
Pollen analysis - Vaux-lès-Saint-Claude (F-39), Eau Morte
Pollen tests in the filling of a circular depression (ice rest, pockmark?) in the heart of a meander of the Bienne. Two samples: 162 and 200 cm deep.
1-(4-Formyl-2,6-dimethoxyphenoxy)-4-chlorobut-2-yne
A reaction of biomass-derived aldehyde synringaldehyde and half an equivalent of 1,4-dichlorobut-2-yne was attempted in order to obtain a bis-aldehyde with an alkyne spacer. The reaction was carried out in a basic media to effect bis O-alkylation, as described in literature for the preparation of ...
4′-(5-Methylfuran-2-yl)-2,2′:6′,2″-terpyridine: A New Ligand Obtained from a Biomass-Derived Aldehyde with Potential Application in Metal-Catalyzed Reactions
The new ligand 4′-(5-methylfuran-2-yl)-2,2′:6′,2″-terpyridine (1) was prepared in one step from 2-acetylpyridine and 5-methylfurfural. The latter is an aldehyde that can be readily obtained from biomass. The new terpyridine molecule was characterized by 1H and 13C-NMR spectroscopy as well as by ...
Diversity-oriented Synthesis of Spiropyrrolo[1, 2-a]isoquinoline Derivatives via Diastereoselective and Regiodivergent Three-component 1,3-Dipolar Cycloaddition Reactions: In vitro and in vivo Evaluation of the Antidiabetic Activity of Rhodanine Analogues
An efficient diastereoselective route is developed to get access to novel spiropyrrolo[1,2-a]isoquinoline-oxindole skeletons by a one-potthree-component [3 + 2] cycloaddition reaction of (Z)-5-arylidene-1,3-thiazolidine-2,4-diones, isatin derivatives, and 1,2,3,4-tetrahydroisoquinoline (THIQ). ...
4,4″-Dichloro-4′-(2-thienyl)-2,2′:6′,2″-terpyridine
A new thiophene-substituted terpyridine derivative has been prepared and characterized. This ligand features a thiophene heterocycle (as an electrochemically polymerizable unit) as well as two chlorine atoms for further functionalization.
4′-(N-(Propan-1,2-dienyl)pyrrol-2-yl)-2,2′:6′,2″-terpyridine
A new pyrrole-substituted terpyridine derivative that possesses an allene moiety was obtained as an “unexpected” sole product during an attempt to alkylate the N-atom of pyrrole with propargyl bromide in order to obtain an alkyne-functionalized terpyridine.
