The solvents were purified according
to the standard procedures. All starting materials were obtained from
Enamine Ltd. Melting points were measured on an automated melting
point system. 1H, 13C, and 19F NMR
spectra were recorded on a Bruker 170 Avance 500 spectrometer (at
500 MHz for protons and 126 MHz for carbon-13) and a Varian Unity
Plus 400 spectrometer (at 400 MHz for protons, 101 MHz for carbon-13,
and 376 MHz for fluorine-19). Tetramethylsilane (1H, 13C) or C6F6 (19F) were used
as standards. Elemental analyses were performed at the Laboratory
of Organic Analysis, Institute of Organic Chemistry, National Academy
of Sciences of Ukraine, and their results were found to be in good
agreement (±0.4%) with the calculated values. Preparative high-performance
liquid chromatography (HPLC) analyses were done on an Agilent 1200
system. Mass spectra were recorded on an Agilent 1100 LCMSD SL instrument
(chemical ionization (APCI)). CCDC-1986046 (10a) and
CCDC-1986047 (20a) contain the supplementary crystallographic
data for this paper. These data can be obtained free of charge from
the Cambridge Crystallographic Data Centre via www.ccdc.cam.ac.uk/data_request/cif.

The solvents were purified according to the standard procedures.[19 ] All the starting materials were obtained from Enamine Ltd. and UORSY. Melting points were measured on MPA100 OptiMelt automated melting point system. Analytical TLC was performed using Polychrom SI F254 plates. 1H, 13C{1H}, 19F, and 11B NMR spectra were recorded on a Agilent ProPulse 600 spectrometer (at 600 MHz for 1H NMR and 151 MHz for 13C NMR), a Bruker 170 Avance 500 spectrometer (at 500 MHz for 1H, 126 MHz for 13C, 470 MHz for 19F, and 160.4 MHz for 11B), or a Varian Unity Plus 400 spectrometer (at 400 MHz for 1H, 101 MHz for 13C, and 376 MHz for 19F). Chemical shifts are reported in ppm downfield from TMS as an internal standard. Elemental analyses were performed on a CHNOS elementary Vario MICRO Cube analyzer. Mass spectra were recorded on an Agilent 1100 LCMSD SL instrument (chemical ionization (APCI)) and Agilent 5890 Series II 5972 GCMS instrument (electron impact ionization (EI)). CCDC deposition number for the structure of 32 is 1993871. The data can be obtained free of charge from The Cambridge Crystallographic Data Centre via www.ccdc.cam.ac.uk/getstructures.

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.
