Abstract:
Introduction: 2-Amino-7-hydroxy-4-phenyl-4H-chromene-3-carbonitrile (4) was synthesized
through a three-component reaction in ethanol/piperidine solution.
Methods: Synthesis of several new 4H-chromenes (5-14) has been achieved involving various reactions.
The structure of these new compounds was confirmed using IR, 1H NMR and 13C NMR, as well as MS
spectroscopy.
Results and Conclusion: All newly substituted chromene derivatives displayed potential analgesic and
anticonvulsant activities. The structure-activity relationship study revealed that 2-amino-4-phenyl-3-(1Htetrazol-
5-yl)-4H-chromen-7-ol (13) was more beneficial than 8-hydroxy-2-methyl-5-phenyl-3,5-dihydro-
4H-chromeno[2,3-d]pyrimidin-4-one (11), 8-hydroxy-2,5-diphenyl-3,5-dihydro-4H-chromeno[2,3-d]pyrimidin-
4-one (12), and 8-hydroxy-5-phenyl-3,5-dihydro-4H-chromeno[2,3-d]pyrimidin-4-one (14) in terms of
analgesic and anti-inflammatory activities.
