Özet
The synthesis of 5,6-O-isopropylidene-1,2-O-(R)-trichloroethylidene-alpha-D-glucofuranose (compound 1) and 5,6-O-isopropylidene-1,2-O-(R)-trichloroethylidene-3-O-(2',3'-epoxypropan-1'-yl)-alpha-D-glucofuranose (compound 2) was carried out. The synthesized compounds 1 and 2were characterized by nuclear magnetic resonance (H-1-NMR), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TG). The FTIR and (HNMR)-H-1 spectra showed that the epoxy group in compound 2 was attached by means of a nucleophilic substitution reaction. The activation energies for thermal degradation of compounds 1 and 2 were calculated from their TG data by using the Kissinger-Akahira-Sunose (KAS) and Tang methods.
