Antimicrobial anthraquinones and triterpenoid isolated from Morinda geminata DC (Rubiaceae)
(2017)
Morinda geminata DC is a plant of the traditional Senegalese pharmacopoeia, the leaves of which are
used in the treatment of various diseases. The phytochemical investigation of its leaves and roots resulted in the
isolation ...
Regioselective Annulation of 1,5-Diketones: Access to Functionalized Hagemann’s Esters
(European Journal of Organic Chemistry, 2000)
The synthesis of the ‘‘functionalized’’ Hagemann’s ester (S)-
18 was investigated. The common starting material in these
approaches was enamino ester (S,Z)-5, which was prepared
through the condensation of keto diester ...
Structural determination of news flavones C-glycosides and trans (S, E)- (-) clovamide isolated Icacina senegalensis Juss leaves (Icacinaceae)
(2013)
Les jeunes feuilles de Icacina senegalensis Juss (Icacinaceae) récoltées en février 2012 dans
l’enceinte de l’Université Assaue Seck de Ziguinchor (Sénégal) sont mis en décotion pendant 4heures dans des
solvants de ...
Sulfonated surfactants obtained from furfural
(2013)
Furfural obtained from pentose containing biomass such as hemicelluloses is subjected to photooxygenation. The resulting hydroxyfuranone obtained in high yields undergoes acetalization with fatty
alcohols. Using NaHSO3, ...
Diastereoselective Addition of Organomagnesium and Organolithium Reagents to Chiral Trifluoromethyl N-tert-Butanesulfinyl Hemiaminals
(2013)
The asymmetric synthesis of trifluoromethylated tertiary and
secondary carbinamines (α,α-dibranched and α-branched
amines) was achieved by reaction of alkyl, aryl and allyl organomagnesium or organolithium reagents to ...
Synthesis and antimalarial activity of cinnamic acid derivatives
(2019)
A peptide coupling reaction between 1-(R)-phenylethylalanine and cinnamic acid derivatives has been
successfully employed for the synthesis of a set of small molecules. The antimalarial activity of these derivative
molecules ...
Case of Charge-Assisted Hydrogen Bonding in the Crystal Structure of Sodium Laurate, Lauric Acid
(2022)
Crystals of Sodium Laurate, Lauric Acid (NaLLA) were obtained and the structure was determined by single-crystal X-ray
difraction. The new crystal form is monoclinic of space group P21/c. The asymmetric unit contains two ...
Evaluation of In Vitro Antiplasmodial Activity of Icacina oliviformis’s (Stems and Roots) and Spondias Purpurea’s (Leaves, Barks And Roots) Extracts from Ziguinchor, Senegal
(2019)
This study was designed to assess phytochemical and antiplasmodial activities of Icacina oliviformis’s and Spondias purpurea’s
extracts. Icacina oliviformis (poiret) Raynal (Icacinaceae) and Spondias purpurea L. (Anacardiaceae) ...
Synthesis and characterization of regioselectively monoderivatized maltooligosaccharides through a combination of tandem mass spectrometry and enzymatic hydrolysis studies
(2013)
Recently, we have designed chemical strategies leading to C-6 perfunctionalized linear maltoheptaose derivatives via the acetolysis of persubstituted β-cyclodextrin (β-CD) at the 6-positions. This approach has now been ...
