The 1H chemical shifts (δ) were expressed in ppm with reference to the residual solvent signal (DMSO-d5, 2.500 ppm and CDCl3, 7.250 ppm relative to the TMS scale), and coupling constants (J) were given in Hertz. In CDCl3 at 300, 400 MHz, resonances of the protons H-5′ and H-6 are overlapping (bold font).
