General Experimental
Procedures. Optical rotations were recorded on a Rudolph Research
Analytical Autopol IV polarimeter using a 0.25 dm cell in the solvent
indicated. NMR spectra were recorded at 25 °C on a 400 MHz Agilent
Inova spectrometer equipped with a 5 mm OneNMR probe. The 1H and 13C NMR chemical shifts were referenced to the solvent
peaks for CDCl3 at δH 7.26 and δC 77.0. NMR FID processing and data interpretation was done
using MestReNova software, version 14.0. High-resolution mass spectra
were recorded on an Agilent 6545 Accurate-Mass Q-TOF LC/MS system
(1290 Infinity II) equipped with a dual AJS ESI source. Preparative-scale
HPLC purification was performed with a Waters Prep LC system, equipped
with a Delta 600 pump and a 996-photodiode array detector using the
Phenomenex Kinetex C8 HPLC column [5 μm, 150 ×
21.2 mm]. All solvents used for chromatography, UV, and MS were HPLC
grade, and the H2O was Millipore Milli-Q PF filtered.

NMR spectra were recorded at 25 °C on either a 500 MHz Bruker Avance spectrometer, equipped with a triple resonance 5mm CPTCI cryo-probe or a 400 MHz Agilent Inova spectrometer equipped with a 5 mm OneNMR probe. NMR spectral processing and data interpretation was done using MestReNova software, version 8.0. Ultra-Performance Liquid Chromatography (UPLC) high resolution mass spectral (HRMS) data were acquired using on a Waters Acquity UPLC system coupled to a Waters LCT Premier TOF mass spectrometer with an electrospray ionization source. Preparative HPLC was run on a Waters Prep LC 4000 system, equipped with a Delta 600 pump and a 996-diode array detector, using a Phenomenex Kinetex C8 or C18 column [5 μ, 150 × 21.2 mm]. All solvents used for chromatography, UV, and MS were GC/LC-MS or HPLC grade, and the H2O for preparative HPLC was Millipore Milli-Q PF filtered.

An Agilent 5530 Accurate Mass Quadrupole Time Of Flight (QTOF) Liquid Chromatography (LC)/ MS (CA, US) was used to obtain high resolution (+) Electrospray Ionization (ESI) MS data. Alltech Davisil 30–40 um 60 Å C18 bonded silica gel (Grace Davison Discovery Sciences, MD, US) was used to adsorb the sample prior to HPLC separation and for Medium Pressure Liquid Chromatography (MPLC) separations. A Merck Hitachi L7100 pump equipped with a Merck Hitachi L7455 Photodiode Array (PDA) detector (Hitachi Ltd., Tokyo, Japan) were also used for HPLC analysis. HPLC columns used include a Thermo Betasil C18 5 μm, 100 Å, 150 mm × 21.2 mm, (Thermofisher Scientific, Massachusetts, US) and a Thermo Betasil C18 5 μm, 100 Å, 250 mm × 10 mm and Phenyl bonded silica HPLC column 5 μm, 100 Å, 250 mm × 21.2 mm (Thermofisher Scientific, Massachusetts, US). Ion exchange chromatography was done using Amberjet 1200H strong acid cation exchanger (Rohm and Haas, Philadelphia, US). The fractions from the HPLC separation were dried using a GeneVac HT-12 centrifugal evaporator (SP Scientific, NY, USA). All solvents used during HPLC and MS were HPLC grade. All solvents used for HPLC and MS were Lab-Scan HPLC grade (RCI Labscan, Bangkok, Thailand), the H2O being Millipore Milli-Q PF filtered. Trifluoroacetic acid (TFA) was spectroscopy grade from Alfa Aesar (Thermofisher Scientific, NY, US).

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.
