Preparation of choline chloride–urea deep eutectic solvent-modified magnetic nanoparticles for synthesis of various 2-amino-4H-pyran derivatives in water solution

A novel hybrid magnetic nanocatalyst was synthesized by covalent coating of Fe3O4 magnetic nanoparticles with choline chloride–urea deep eutectic solvent using 3-iodopropyltrimethoxysilane as a linker. The structure of this new catal

FURANS AND PYRANS FROM γ- AND δ-KETONITRILES

The spontaneous cyclization of δ-ketonitriles resulting from the reaction of malononitrile with either 1,2,3-triaryl-3-chloropropanones (II) or 1,2,3-triarylpropenones (III) in a basic medium leads to 2-amino-4,5,6-triaryl-3-cyano-4H-pyrans (V).On the other hand II and III react with potassium cyanide and an aromatic aldehyde in a hydroalcoholic medium to give γ-ketonitriles which cyclize to 2-arylideneimino-3,4,5-triarylfurans (VIII).
