Sekundarni naslov: | Synthesis of unnatural phenylalanine derivatives and their incorporoation into biologically relevant peptides |
Sekundarni povzetek: | I synthesized polyiodinated derivatives of L-phenylalanine, as well as N-Fmoc-3,4-diiodophenylalanine from the natural amino acid. I intended to further convert these compounds into their respective polyboronated derivatives, which I intended to introduce into polypeptide chains via SPPS. I used L-phenylalanine as the starting material which I iodinated via electrophilic aromatic substitution with potassium iodate and elemental iodine under strongly acidic conditions. Thereafter I used flash column chromatography to separate the di- and triiodinated products. I introduced the Fmoc protecting group to the crude product through a reaction in a mixed aqueous-organic medium with the use of N-(9-fluorenylmethoxycarbonyloxy) succinimide. The diiodinated product was then isolated with normal-phase column chromatography. The synthesized compounds haven’t been reported in literature yet. I also synthesized N-Fmoc-L-4-boronophenylalanine from pure L-4-boronophenylalanine with the use of the (9H-fluorenyl)methyl ester of chloroformic acid. I also attempted the synthesis of native human insulin from independently prepared polypeptide chains that I obtained through SPPS. |
