Structurally diverse aromatic aldehydes

In this study, the selective oximation of structurally diverse aromatic aldehydes (versus ketones) to the corresponding aldoxime derivatives was investigated using the combination system of NH2OH·HCl and bis-thiourea complexes of cobalt, nickel, copper and zinc chlorides, MII(tu)2Cl2, in a mixture of CH3CN-H2O (1:1).

In this study, a green and practical approach towards Hantzsch dihydropyridine synthesis of acridine-1,8-diones is introduced. Via the mentioned protocol, the one-pot condensation reaction of structurally diverse aromatic aldehydes, dimedone and NH4OAc was promoted by microwave radiation at solvent and catalyst-free conditions.
