Abstract: Two novel oligosaccharides, mono- and difructosyllactosucrose {[O-β-D-fructofuranosyl-(2 1)]n-β-D-fructofuranosyl-O-[β-D-galactopyranosyl-(1 4)]-α-D-glucopyranoside, n = 1 and 2} were synthesized using 1F-fructosyltransferase purified form roots of asparagus (Asparagus officinalis L.). Their 1H and 13C NMR spectra were assigned using several NMR techniques. The spectral analysis was started from two anomeric methines of aldose units, galactose and glucose, since they showed separate characteristic signals in their 1H and 13C NMR spectra. After assignments of all the 1H and 13C signals of two units of aldose, they were discriminated as galactose and glucose using proton–proton coupling constants. The HMBC spectrum revealed the galactose residue attached to C-4 of glucose, fructose residue attached to the C-1 of glucose, and further fructosyl fructose linkage extended from the glucosyl fructose residues.

TL;DR: In this article, a three-component one-pot reaction of thiazole Schiff's bases, ammonium acetate and an aldose, under solvent-free microwave irradiation, expeditiously and diastereoselectively yield acyclic C-nucleosides incorporating the thiazolo-striazine structure as a nucleobase.
