《Synthesis and evaluation of antimicrobial and antioxidant activity of novel 7-Aryl-6H,7H-benzo[f]chromeno[4,3-b]chromen-6-one by MgO nanoparticle as green catalyst》 was published in Journal of Heterocyclic Chemistry in 2020. These research results belong to Hosseinzadegan, Sara; Hazeri, Nourallah; Maghsoodlou, Malek T.. Formula: C8H8O3 The article mentions the following:
Novel 7-aryl-6H,7H-benzo[f]chromeno[4,3-b]chromen-6-one derivatives I [R = C6H5, 4-MeOC6H4, 3-O2NC6H4, etc.] were synthesized via multicomponent reaction of 2-naphthol, aldehyde derivatives, 4-hydroxycoumarin using MgO nanoparticles as a recyclable and efficient catalyst. This method offered some benefits such as shorter time, high yields and concordance with green chem. All the synthesized compounds were evaluated for their antibacterial, antifungal and antioxidant activities. The results came from multiple reactions, including the reaction of 2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3Formula: C8H8O3)
2-Hydroxy-4-methoxybenzaldehyde(cas: 673-22-3) is employed in the synthesis of Schiff base ligand. It is applied as a reactant in the synthesis of LPA1R antagonists used in the inhibition of LPA-induced proliferation and contraction of normal human lung fibroblasts. Also used in the synthesis of tyrosine kinase 6 proteinase inhibitors.Formula: C8H8O3
