“…Since aldehyde functional groups exist in most of the MCRs strategies as an integral component, dialdehyde cellulose, which is directly prepared via oxidation of cellulose derivatives with NaIO 4 or KIO 4 , undoubtedly plays a dominant role as a readily available component in MCRs. Furthermore, due to utmost importance of green media such as water, polyethylene glycol, deep eutectic solvents, ionic liquids, and solvent-free conditions in chemical transformation, − MCRs are generally carried out in these eco-friendly media without any catalyst or high temperature, apart from a few exceptions, which could make them both academically and industrially more attractive and practical for the modification of cellulose . As a matter of fact, dialdehyde cellulose has the appropriate solubility in water, which means that many MCRs like Passerini, Ugi, and a vast number of unnamed reactions can be successfully conducted in water as the greenest solvent.…”

With increasing ecological and environmental concerns because of the extensive use of petroleum-based products, the use of natural resources for preparation of functional materials is of great public value. Cellulose is introduced as an ideal and promising biomaterial for widespread application which is obtained from biobased sources such as plants, biomass, or bacteria, relying on efficient, scalable, and facile methods. Generally, sulfation, silylation, esterification, phosphorylation, etherification, and oxidation are common reactions that were applied for functionalization of cellulose; however, multicomponent reactions (MCRs), surmised as versatile and assorted approaches, have been deployed for the modification of cellulose. The functionalized celluloses enjoyed various unique phenomena and properties which render them promising biomaterials for various applications ranging from biomedicine to catalysis. Herein, diverse types of prominent MCRs encompassing Biginelli, Hantzsch, Kabachnik−Fields, and Betti, as well as two paramount isocyanide-based MCRs, namely, Passerini and Ugi, have been used in cellulose functionalization. MCRs, which have emerged as significant platforms to generate cellulose-based materials with new properties, are reviewed here with special emphasis on modification, functionalization, and cutting-edge applications such as drug delivery, catalysis, C−H functionalization reaction, and emulsifier, among others.

Reducing the use of solvents is an important aim of green chemistry. Using micelles self-assembled from amphiphilic molecules dispersed in water (considered a green solvent) has facilitated reactions of organic compounds. When performing reactions in micelles, the hydrophobic effect can considerably accelerate apparent reaction rates, as well as enhance selectivity. Here, we review micellar reaction media and their potential role in sustainable chemical production. The focus of this review is applications of engineered amphiphilic systems for reactions (surface-active ionic liquids, designer surfactants, and block copolymers) as reaction media. Micelles are a versatile platform for performing a large array of organic chemistries using water as the bulk solvent. Building on this foundation, synthetic sequences combining several reaction steps in one pot have been developed. Telescoping multiple reactions can reduce solvent waste by limiting the volume of solvents, as well as eliminating purification processes. Thus, in particular, we review recent advances in “one-pot” multistep reactions achieved using micellar reaction media with potential applications in medicinal chemistry and agrochemistry. Photocatalyzed reactions in micellar reaction media are also discussed. In addition to the use of micelles, we emphasize the process (steps to isolate the product and reuse the catalyst).
