Chemicals were purchased from commercial suppliers
and used as received. Melting points were taken on a Stuart Scientific
200 SIMP3 apparatus and are uncorrected. Silica gel plates (Merck
F254) and silica gel 60 (Merck, 230–400 mesh) were
used for TLC and flash chromatographies (FC), respectively; petroleum
ether (PE) employed for crystallization and chromatographic workup
refers to the fraction of bp 30–50 and 40–70 °C,
respectively. IR spectra were recorded with a Shimadzu FT-IR 84 00S
spectrophotometer. 1H and 13C NMR spectra were
recorded with Varian Mercuryplus 400 and Varian Inova instruments,
operating at 400 and 100 MHz, respectively. Elemental analyses were
performed with Thermoscientific FlashSmart elemental analyzer CHNS/O.

Anhydrous solvents were
prepared according to the standard techniques. Commercially available
reagents were used without further purification. Melting points were
recorded on a Büchi B-540 apparatus and are uncorrected. Chromatographic
separations were performed under pressure on silica gel (Merck 70–230
mesh) by using flash column techniques; Rf values refer to TLC carried out on 0.25 mm silica gel plates (F254) with the same eluent as that indicated for column chromatography. 1H NMR (200 or 400 MHz) and 13C{1H} NMR
(100.4 MHz) spectra were recorded either on Varian Inova (400 MHz)
or Mercury (200 or 400 MHz) spectrometers in the specified deuterated
solvent at 25 °C. Solvent reference lines were set at 7.26 and
77.00 (CDCl3) in 1H and 13C{1H} NMR spectra, respectively. Mass spectra were recorded by
direct inlet of a 20 ppm solution in CH3OH on an LCQ Fleet
Ion Trap LC/MS system (Thermo Fisher Scientific) with an ESI interface
in the positive ion mode. Microanalyses were carried out with a Thermo
Scientific FlashSmart Elemental Analyzer CHNS/O. Acetates 9(35 (link)) and 22(12 (link)) are known.

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.
