Solvents and fine chemicals
were obtained from commercial sources and utilized with no additional
purification. A Fisher melting apparatus was used to determine melting
points that are uncorrected. A JEOL a 500 MHz NMR spectrometer at
the Faculty of Science, Mansoura University, was used to record the 1H NMR (500 MHz) and 13C NMR (125 MHz) spectra using
DMSO-d6, D2O, and CDCl3 as solvents. On the other hand, a Bruker 400 MHz NMR spectrometer
at the Faculty of Science, Zagazig University, was used to record
the 1H NMR (400 MHz) and 13C NMR (100 MHz) spectra
using DMSO-d6 as a solvent. Chemical shifts
(δ) are given in ppm, and coupling constants (J) are reported in Hz. Elemental analyses were performed at the Regional
Center for Mycology & Biotechnology, Al-Azhar University, on a
Thermo Fisher Flash 2000 CHNS analyzer. The progress of the reactions
was checked by (TLC), and short-length UV irradiation was used for
visualization.
