^aSignal of the Ac⁻ δ1.90–1.91 for 7a–12a; signal of the Ac δ 2.02–2.05 for 7b-12b.

^bThe NMR spectra were acquired at the temperature of 303–310 K. For each compound the temperature was chosen so that to exclude the overlap of the solvent signal (HOD) with signals of the anomeric protons in ¹H NMR spectrum.
