Sažetak
Over the last few years, deep eutectic solvents (DESs) have been proven to be an excellent green reaction media for various heterocycles. DESs are a mixture of two or three components which mixed together form a low melting-point mixtures. DESs in regards to organic solvents have more advantages such as non-toxicity, thermal stability, biodegradability, low vapour pressure and price. DESs are composed of a hydrogen bond acceptor (HBA) (usually choline chloride) and a hydrogen bond donor (HBD) components, such as sugars, amides, alcohols and carboxylic acids. Mixing of these species forms strong hydrogen bond interactions. Quinazolinones are heterocycles with a wide range of biological activities. Herein, we peformed a condensation of anthranilic acid, p- chloroaniline and trimethyl orthoformate into 3-(4-chlorophenyl)quinazolin-4(3H)-one. A screening of different choline chloride based deep eutectic solvents has been carried out to determine a favorable solvent for this synthesis as environmentally friendly procedure without hazardous solvents and catalysts.
