: An efficient methodology for the synthesis of 1,3-thiazolidin-4-ones using L-Proline as catalyst under aqueous conditions has been developed. The one-pot, multicomponent reaction of aromatic/heterocyclic aldehyde, aromatic amine and thioglycolic acid at room temperature give 1,3-thiazolidin-4-ones in moderate to good yields. Further, the current approach is notably greener than traditional methods with E-factor of 3.1 and the eco scale score of 96. The developed protocol offers several features, such as being simple, environmentally benign, energy-efficient, economical, mild conditions, shorter reaction time.

Intense Research

The catalytic conversion of (ligno)cellulose is currently subject of intense research. Isosorbide is one of the interesting products that can be produced from (ligno)cellulose as it can be used for the synthesis of a wide range of pharmaceuticals, chemicals, and polymers. Isosorbide is obtained after the hydrolysis of cellulose to glucose, followed by the hydrogenation of glucose to sorbitol that is then dehydrated to isosorbide. The one-pot process requires an acid and a hydrogenation catalyst. Several parameters are of importance during the direct conversion of (ligno)cellulose such as the acidity, the crystallinity and the particle size of cellulose as well as the nature of the feedstocks. This review highlights all these parameters and all the strategies employed to produce isosorbide from (ligno)cellulose in a one-pot process.

AbstractDifferent supported metal catalysts were tested for the one-pot transformation of corncob xylan to xylitol. The influence of several factors, such as catalytic support, nature of metal, metal loading, amount of catalyst, hydrogen pressure and reaction temperature, was investigated. The results revealed that xylan can be converted into xylitol with a yield close to 80% after 2 h of reaction using Ru supported on carbon nanotubes (CNT, 0.4 wt% metal loading) with excellent stability after repeated use, at a temperature of 170°C and an H
