- Title

- Abstract
A novel deep eutectic solvent system was prepared by mixing choline chloride as a hydrogen-bond acceptor with 2,2-bis(hydroxymethyl)propane-1,3-diol (pentaerythritol) as a hydrogen-bond donor. This green solvent was used for the one-pot synthesis of pyran and chromene derivatives from aromatic aldehydes, 1,3-dicarbonyl compounds, and malononitrile. The solvent was readily recycled and can be reused three times without significant loss of activity or mass. This procedure offers advantages such as environmental friendliness, shorter reaction times, and higher yields.
