The starting material 7-hydroxy-4-methylcoumarin was bought from Sigma-Aldrich and used as received. Chemical characterization was used as following instruments such as Shimadzu 8201 pc for IR spectra on KBr pellets at 4000–400 cm−1, Bruker DRX instrument at 300 MHz was used to inspect 1H & 13C NMR spectra. The elements C, H, N present in synthetic compounds were analyzed with Elemental analyzer (Varian EL III). Thin layer chromatography (TLC) was used to check the purity of the compounds.

The chemicals 7-hydroxy-4-methylcoumarin, tyrosinase, and bergapten were purchased from Sigma-Aldrich and used without further purification. Melting points were recorded in open capillary tubes and were uncorrected. The IR spectra (KBr) were recorded in KBr on a Shimadzu 8201 pc (4000–400 cm−1). The 1H NMR and 13C NMR spectra were recorded on a Bruker DRX-300 MHz. Elemental analysis (C, H, and N) was performed using an Elemental analyzer model (Varian EL III). The purity of the compounds was checked via thin layer chromatography (TLC) with silica gel plates.

4-Methylumbelliferone, 7-hydroxy-4-methylcoumarin, 11-bromoundecanol, diethylether, ethanol, acetone, p-toluenesulfonyl chloride, piperidine, pyridine, methacryloyl chloride, 2,2'-azobis(2methylpropionitrile) (AIBN) MgSO4, potassium carbonate (K2CO3) and dodecanethiol (DDT) were purchased from Sigma Aldrich and used without further purification. 2-ethylhexyl methacrylate was purchased from Alfa Aesar. 2-Methyl-2-oxazoline (MOXA), 2-phenyl-2oxazoline (PhOXA), 2-n-butyl-2-oxazoline (BuOXA) and acetonitrile were distilled over CaH2 just prior to use. methacryloyl chloride was distilled under reduced pressure before use. Coumarin tosylate (CoumOTs) was synthesized and purified by recrystallization according to previously published protocols 26 . Acetonitrile and chloroform were distilled over CaH2 and stored in nitrogen.
All other commercial reagents and solvents were used as received. Ultrapure water was obtained from an ELGA Purelab Flex system (resistivity greater than 18.2 MΩ.cm) and was filtered on 0.2 m RC filters just before use. 1 H and 13 C NMR Spectra were recorded using a Bruker Avance 300 MHz spectrometer.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
