All chemicals and reagents were purchased from Tokyo Chemical Industry (Tokyo, Japan) and Sigma-Aldrich (St. Louis, MO) and used without further purification. Fourier-transform infrared (FT-IR) spectra were recorded on NICOLET 380. 1H (400 MHz) and 13C (100 MHz) NMR of all synthesized compounds were recorded on Bruker Magnet System 400′54 Ascend. Gas Chromatography–Mass Spectrometry spectra were performed on Shimadzu GC-1010 Plus GCMS-QP2010 SE. High-resolution Mass Spectrometry (HR-MS) data were performed on 6530Accurate-Mass Q-TOF LC/MS. Spectrofluorometer spectra were performed on Spectramax M2; Molecular Devices, Sunnyvale, CA, USA.

The reagents were purchased from commercial chemical reagent companies and used without further purification. Column chromatography was carried out on silica gel (200–300 mesh). 1H NMR and 13C NMR spectra were recorded on a 400 MHz spectrometer (Bruker Magnet System 400’ 54 Ascend). Melting points were measured on a BUCHI B-540 and uncorrected. HRMS (ESI) was recorded using Agilent 6520 accurate-Mass Q-TOF LC/MS system (1200–6520/Agilent).
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.
