    - The starting materials and reagents used in the reactions were supplied commercially by Aldrich, Acros, ABCR, and Merck. - Nuclear magnetic resonance (1H-NMR, 13C-NMR) spectra were recorded using a Bruker Advance III 500 MHz spectrometer in DMSO-d6. Chemical shifts are reported in parts per million (ppm), and the coupling constants (J) are expressed in Hertz (Hz). The addition of D2O confirmed the assignment of exchangeable protons (NH). - Melting points (mp) were measured in open capillary tubes and are uncorrected using a Gallenkamp MPD350.BM3.5 apparatus. - Thin-layer chromatography (TLC) was performed on silica 60 F254.
