The hydantoin moiety is found in several bioactive compounds with important pharmacological properties such as antimicrobial, antifungal, anti-androgens, anticancer and the historical action anticonvulsant. Because of these reasons, the synthesis of these compounds and their derivatives is important to review considering the philosophy of the green chemistry. In this review, we present the actual importance in the green synthesis of hydantoins and their derivatives using green methods, such as microwave and ultrasound irradiation, ionic liquids, solid-phase and solvent-free synthesis. Finally, several green protocols reported have been discussed.

Nanotechnology is the most sought field in biomedical research. Metallic nanoparticles have wide applications in the medical field and have gained the attention of various researchers for advanced research for their application in pharmaceutical field. A variety of metallic nanoparticles like gold, silver, platinum, palladium, copper and zinc have been developed so far. There are different methods to synthesize metallic nanoparticles like chemical, physical, and green synthesis methods. Chemical and physical approaches suffer from certain drawbacks whereas green synthesis is emerging as a nontoxic and eco-friendly approach in production of metallic nanoparticles. Green synthesis is further divided into different approaches like synthesis via bacteria, fungi, algae, and plants. These approaches have their own advantages and disadvantages. In this article, we have described various metallic nanoparticles, different modes of green synthesis and brief description about different metabolites present in plant that act as reducing agents in green synthesis of metallic nanoparticles.

: Green chemistry emphasizes designing novel routes to overcome health and environmental problems that occur during a chemical reaction. Green solvents are used in place of conventional solvents that are hazardous to both human and the environment. Solvents like water, ionic liquids, supercritical CO2, biosolvents, organic carbonates, and deep eutectic mixtures can be used as green solvents. The review focuses on the properties, applications, and limitations of these solvents.

Alum (KAl(SO4)2·12H2O) is an inexpensive, efficient, and nontoxic catalyst used for the synthesis of 2-[3-amino-5-methyl-5-(pyridin-3-yl)-1,5-dihydro-4H-1,2,4-triazol-4-yl]propanoic acid derivatives in aqueous media by the reaction of 3-acetyl pyridine(1), amino acids(2)/(6), and thiosemicarbazide(4)at 80°C. This methodology offers significant improvements for the synthesis of products with regards to the yield of products, simplicity in operation, and green aspects by avoiding toxic catalysts which uphold the motto of green chemistry. Synthesized compounds have been characterized by FT-IR,13C NMR, and1HNMR spectroscopy.

Solvent Free Reaction

Tertiary α-hydroxyphosphine oxides have been synthesized via the catalyst- and solvent-free reaction between available secondary phosphine oxides and aliphatic, aromatic and heteroaromatic ketones at 20–62 °C in near to 96–98% yield. The developed method meets the requirements of green chemistry and the PASE (pot, atom, step economy) paradigm. According to quantum-chemical calculations at the B3LYP/6-311++G(d,p) level, the synthesized hydroxyphosphine oxides feature a weak (≈3 kcal·mol–1) O−H···O=P intramolecular hydrogen bond.
