Özet:

 


 
                         In this study, 3,4-dihydroxy-L-phenylalanine (L-Dopa) was 
solvothermally polymerized to monodisperse microspheres 1 μμm in 
diameter. Polymerization was carried out in dimethylformamide containing 
appropriate amounts of urea and L-Dopa at 120 ∘∘C for 24 h. 
Synthesis of the polymer in basic aqueous solution under hydrothermal 
conditions or via conventional heating resulted in the formation of bulky 
powders including irregularly shaped particles of the polymer. The 
morphologies of the synthesized polymers were characterized by scanning 
electron microscopy (SEM). The microspheres synthesized by solvothermal 
method (with ∼∼1 μμm average diameter) were clearly observable in 
SEM micrographs. The thermal stability of the synthesized polymer was 
studied by thermogravimetry and differential scanning calorimetry 
techniques. It was recognized that the polymer is thermally stable at more 
than 200 ∘∘C. Applicability of the polymer microspheres was 
investigated for catalyzing the reaction of one-pot multicomponent synthesis 
of dihydrofurans. Several dihydrofuran derivatives were successfully 
synthesized using poly L-Dopa as a novel, environmentally friendly, and 
efficient catalyst with efficiency of more than 90%. Poly L-Dopa is 
easily separated by filtration from the reaction mixture. It can be used 
several times without decreasing the catalyzing activity after washing by 
suitable solvents.
