“…In contrast, cinnamaldehydes bearing an electron-withdrawing chloride-or nitro-substituent gave conversions and selectivities of 63%-78% and 72%-85%, respectively, (Table 3, entries 6-12) even after a longer reaction time (180 min). The results in Table 3 also showed that the formation of weak interactions between β-CD and the substrates enhanced their reactivity depending on the size, shape and hydrophobicity of the guest molecule [3,56].…”

“…The weak interactions between the active phase and lignin support efficiently favored oxidation reaction of benzyl alcohol. The catalysts also demonstrated good recyclability, with no appreciable loss of catalytic activity, making it suitable to be used for green synthesis of benzaldehyde [87]. Chen and collaborators found a different way to use lignin as catalyst support, namely by forming a lignin-phenolic resin employed as support for palladium nanoparticles.…”

Heterogeneous catalysts are progressively expanding their field of application, from high-throughput reactions for traditional industrial chemistry with production volumes reaching millions of tons per year, a sector in which they are key players, to more niche applications for the production of fine chemicals. These novel applications require a progressive utilization reduction of fossil feedstocks, in favor of renewable ones. Biomasses are the most accessible source of organic precursors, having as advantage their low cost and even distribution across the globe. Unfortunately, they are intrinsically inhomogeneous in nature and their efficient exploitation requires novel catalysts. In this process, an accurate design of the active phase performing the reaction is important; nevertheless, we are often neglecting the importance of the support in guaranteeing stable performances and improving catalytic activity. This review has the goal of gathering and highlighting the cases in which the supports (either derived or not from biomass wastes) share the worth of performing the catalysis with the active phase, for those reactions involving the synthesis of fine chemicals starting from biomasses as feedstocks.

Cyclodextrins are well-known macrocyclic oligosaccharides that consist of α-(1,4) linked glucose units and have been widely used as artificial enzymes, chiral separators, chemical sensors, and drug excipients, owing to their hydrophobic and chiral interiors. Due to their remarkable inclusion capabilities with small organic molecules, more recent interests focus on organic reactions catalyzed by cyclodextrins. This contribution outlines the current progress in cyclodextrin-catalyzed organic reactions. Particular emphases are given to the organic reaction mechanisms and their applications. In the end, the future directions of research in this field are proposed.
