Transcript of Chalcone Synthesis

Chalcone Synthesis
By: Jerry Sicalo, & Sandy Barakat

Benefits
Antioxidant
-Works to eliminate free radicals

-Exists in teas, fruits, wine

-Helps protect against diseases

-Used to treat antiviral and antimicrobial activities
Chalcone Synthesis
4-Chlorochalcone
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

Further Experimentation
Synthesis of Cyclo-2-enone
Cyclo-2-enone synthesized using Beta Dicarbonyl, benzyl alcohol, and KOH using the alternative microwave procedure.
TLC
Silica was added to the product
Lyophilizer used to remove benzyl-alcohol

Further procedure:
Silica using column, recrystalize

Outline
Benefits
Chalcone Synthesis
Data
Further Analysis
Anthocyanins
MICHAEL ALDOL CONDENSATION REACTION
Function
-pH Indicator

-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
Chalcone
WHAT IS IT?
Flavonoids
Physical Properties:
Chalcone is isomerized by Chalcone synthase enzyme which produces pigment
Color varies with pH
Anthocyanins
