Background Potato (Solanum tuberosum) is the fourth culture in the world and is widely used in the agri-food industries. They generate by-products in which α-chaconine and α-solanine, the two major solanidine-based glycoalkaloids of potato, are pre

While present in large numbers in nature, studies on the physical chemical aspects of glycosteroids are quite rare and focused on cholesterol, and all compounds studied thus far have shown liquid crystalline properties in a narrow temperature range.

The transesterification of 3-[(β-cyclodextrinyl)succinamido]propane-1,2-diol with fatty esters catalyzed by immobilized lipase from Mucor miehei occurred with very different conversions of the two diastereoisomers [(R)- or (S)-amidopropanediol]. The

The mesophasic properties of S-alkylthiohexonolactones ( d -galactono- and d -mannono-) and the corresponding itol derivatives with general formula Su-SR (R = C11H23) have been investigated. The observation that the synthesized compounds of this seri

Syntheses of 6-amino-6-deoxy-2,3- O -isopropylidene- d -gulono- and l -gulono-1,6-lactams 3 and 4 from corresponding glycono-1,4-lactones are described. Activation of the primary hydroxyl group requires 5,6-cyclic sulfite intermediate to obtain 6-azi

6-Azido-6-deoxy- d -galactitol and d -mannitol were obtained quantitatively via the reduction of the corresponding 6-azido-6-deoxy- d -hexono-1,4-lactones, and 6-azido-6-deoxy- d -glucitol was obtained by the reduction of 6-azido-6-deoxyglucose in go

Alkylthio- l -galactitols and d -mannitols were obtained in good yields (70–81%) by reduction, with NaBH4, of the corresponding 6-S-alkyl-6-thio- d -hexono-1,4-lactones.

5-Thio-D-arabinopyranose (5) and 5-thio-D-xylopyranose (10) were synthesized from the corresponding D-pentono-1,4-lactones. After regioselective bromination at C-5, transformation into 5-S-acetyl-5-thio derivatives, reduction into lactols and deprote

Mesophasic properties of S-alkylthiopentonolactones (D-ribono, D-arabinono and D-xylono) and the corresponding itol derivatives with general formula Su-SR (R=n-CnH2n+1) are studied. It was shown that the thermotropic and lyotropic phase transition te

5-Thio-D-ribopyranose was synthesized from D-ribono-1,4-lactone (1) by two approaches: (i) 5-bromo-5-deoxy-D-ribono-1,4-lactone (2) was successively transformed into 5-bromo-5-deoxy, 5-S-acetyl-5-thio or 5-thiocyanato-D-ribofuranose derivatives; appr
