Transcript of Chalcone Synthesis
By: Jerry Sicalo, & Sandy Barakat
-Works to eliminate free radicals
-Exists in teas, fruits, wine
-Helps protect against diseases
-Used to treat antiviral and antimicrobial activities
Synthesized using Benzaldehyde 4-Chloroacetophenon in reagent Ethanol
NaOH and Water added, filtered, dried, then recrystalized.
Data & Results
NMR, IR, & Melting point were obtained
True melting point of 4-chlorochalcone: 94-96 Degrees Celcius
Melting point obtained of product: 96-99 Degrees Celcius
Synthesis of Cyclo-2-enone
Cyclo-2-enone synthesized using Beta Dicarbonyl, benzyl alcohol, and KOH using the alternative microwave procedure.
Silica was added to the product
Lyophilizer used to remove benzyl-alcohol
Silica using column, recrystalize
MICHAEL ALDOL CONDENSATION REACTION
-Pigment that gives plant leaves and fruit it's color
Attracts pollinators and animals
-Used in Solar cells (converts light to electrical energy
Water-Soluble vacuolar pigment
Found naturally occuring in plants
WHAT IS IT?
Chalcone is isomerized by Chalcone synthase enzyme which produces pigment
Color varies with pH
