Green approach using water mediated Diels-Alder reaction for the synthesis of some 2-(4-bromo-1-naphthyl)-3-(aryl) bicyclo[2.2.1]hept-5-ene methanones and evaluation of their antimicrobial and antioxidant activities

Abstract: Some (4-bromo-1-naphthyl)-(3-(substituted phenyl) bicyclo[2.2.1]hept-5-en-2-yl) methyl ketones were synthesized by fly-ash catalyzed environmentally benign Diels-Alder [4+2] cycloaddition reaction of 4-bromo-1-naphthyl chalcones and cyclopentadiene in water medium. In this reaction, the obtained yield was more than 60%. The synthesized methanones were characterized by their physical constants, microanalysis, infrared, nuclear magnetic resonance and mass spectroscopic data. The antibacterial and antifungal acti… Show more

“…The bicyclo naphthyl‐based chalcone derivatives 81 a – i (Figure 14) were reported by Thirunarayanan et al . and analyzed for their biological activities [130] . Compounds 81 c and 81 d effectively inhibited all bacterial strains, with high activity for B. subtilis due to electron‐donor 4‐methoxy substitution, increased potency due to electron‐withdrawing 4‐chloro substitution, and a minimal amino group.…”

“…In this way, a wide range of substituents can be readily considered for the guanidine moiety, representing the stepwise synthesis. These substituents are likely to have the additional donor atoms; these atoms are likely to play important roles in the coordination of guanidine toward the metal center [30][31][32] .…”
