Synthesis and Antimalarial Activity of 1,4-Disubstituted Piperidine Derivatives
(2020)
In order to prepare, at low cost, new compounds active against Plasmodium falciparum, and
with a less side-effects, we have designed and synthesized a library of 1,4-disubstituted piperidine
derivatives from 4-aminopiperidine ...
Dinuclear zinc complexes using a set of two polytadenate phenolate ligands and applications in polymerization of catalysis of D,L-Lactone
(2021)
The synthesis and characterization of 9 dinuclear zinc complexes are reported, including the X-ray crystal
structures of 5 complexes. The set of three ligand motif (R) -2,6-bis((E) -((2-(dimethylamino) ethyl) imino)
methyl) ...
Activité Anti-Hyperglycémiante Et Élucidation Structurale Des Composés Isolés Des Feuilles De Spondias Purpurea L. (Anacardiaceae)
(2017)
Spondias purpurea L. (Anacardiaceae) is a Senegalese traditional
pharmacopoeia plant, which leaves are used in the treatment of various
diseases. The leaves’ ethanolic extract exhibited antihyperglycemic activity
on ...
Electrospray ionization mass spectrometry: a key analytical tool for the characterization of regioselectively derivatized maltooligosaccharides obtained starting from natural b-cyclodextrin
(Published online in Wiley InterScience (www.interscience.wiley.com). DOI: 10.1002/rcm.2369, 2006)
The development of natural cyclodextrins (CDs) for various industrial applications (agroalimentary,
cosmetic or pharmaceutical) constitutes a continuous challenge. For the integration of these agricultural plant products ...
Synthesis and evaluation of the antimalarial activity of cinnamic acids derived from piperidine
(2019)
The synthesis and antimalarial activity of 1, 4-aminopiperidine derived cinnamic acids are described. Different
analogs are prepared from reductive amination reactions and SN1 substitutions. These analogs are tested ...
Faidherbia albida Del. (Leguminosae), is a plant of the Senegal traditional pharmacopoeia whose leaves and bark are used in the treatment of various diseases. Investigation on Faidherbia albida Del. resulted in the isolation two glycosyl flavones 1 and 2. The isolated compounds were characterized by NMR and mass-spectrometry. The present study constitutes the first phytochemical examination of the barks of Faidherbia albida Del.

Stereoselective Triplet-Sensitised Radical Reactions of Furanone Derivatives
(2010)
The stereo- and regioselectivity of triplet-sensitised radical reactions of furanone derivatives have been investigated. Furanones 7 a,b were excited to the 3 pp* state by triplet energy transfer from acetone. Intramolecular ...
Synthesis of N-Substituted piperidines from piperidone
(2015)
A reductive amination reaction between N-boc-piperidin-4-one and 3,4-dichloroaniline was successfully
employed for the synthesis of the N-(3,4-dichloropheny)-N-(2-phenoxylethyl) piperidin-4-amine. The synthesis of a
small ...
Synthesis of 1,2,3-triazole containing derivative of peperidine
(2020)
A reductive amination reaction between N-Boc -piperidin-4-one and phenoxy-ethylamine was successfully used
for the synthesis of (5-Methyl-2-phenyl-2H-[1,2,3] triazol-4ylmethyl)- (2-phenoxy-ethyl)-piperidin-4-yl-amine.
The ...
