Microwave assisted synthesis of some new heterocyclic spiro-derivatives with potential antimicrobial and antioxidant activity.
Homophthalic anhydride reacts with different aromatic amines to produce N-substituted homophthalimides. Bromination of the latter produces 4,4-dibromo-homophthalimide derivatives that can be used as precursors for spiro-derivatives. The dibromo derivatives react with different binucleophilic reagents to produce several spiro-isoquinoline derivatives. Reaction of the dibromo derivatives with mal...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Synthesis and Antimicrobial Activity of Some New Isatin Derivatives
Some new 3-[(5-benzylidene-2-phenyl)-3, 5-dihydro-4-H-imidazol-4-one-3-(4-bezoylhydrazono)]-indole-2-ones (VIII) have been synthesized from different isatinhydrazones (II) by condensing with 2-phenyl-5-benzylidene- 3-N (4-acetyl phenyl)-1, 5-dihydro-imidazol-4-one (VII). Their chemical structures have been confirmed by IR, 1HNMR, MASS and by elemental analysis. Investigation of antimicrobial ac...

متن کاملSynthesis and Preliminary Bioassays of Some Bis -1,3 - Benzoxazines
Four previously synthesized (R =-F,-F,-CI,-Br,-l) and one new (R=-H) 3,3' -ethylene-bis(3,4-dihydro-6R-2H-1,3-benzoxa2Íne) were preliminary tested for insecticidal activity against M. domestica (Díptera) and C. cary (Lepidoptera) larvae. Under laboratory conditions no toxic action was observed. All larvae continued development and pupated successfully but internal or external malformations were...
