Abstract

1, 10-PHENANTHROLINE entails several appealing structural and chemical properties: basicity, rigidity, aromaticity, planarity, and chelating capability. This makes it a versatile catalystin organic chemistry. An efficient and environmentally friendly method for the synthesis oftetrahydrobenzo[b]pyrans as important pharmaceutical compounds has been developed usingPHENANTHROLINE (%5 mol) as an organocatalyst. A mixture of an aromatic aldehyde, malononitrile, and 1, 3-dicarbonyl compounds in the presence of the PHENANTHROLINE as homogeneous catalyst at50º in H2O/EtOH resulted in excellent yields of the corresponding products. This new methodologyis of interest due to use of aqueous media as a green solvent system, its short reaction time, highyields, and no further purification.
