First total synthesis of 25(R)-ruscogenin-1-yl β-D-xylopyranosyl-(1→3)-[β-D-glucopyranosyl-(1→2)]-β-D-fucopyranoside, an ophiopogonis saponin from the tuber of Liriope muscari (Decne.)
TL;DR: The first total synthesis of 25(R)-ruscogenin-1-yl β-D-xylopyranosyl-(1→3)-[β-D]-glucopyrano-ylpoly(1→2)]-β -D-fucoparanoside (1), an Ophiopogonis saponin with strong anti-inflammatory and immunopharmacological activities from the tuber of Liriope muscari, was described in this paper.

Synthesis of the namenamicin A–C disaccharide: towards the total synthesis of namenamicin
TL;DR: In this paper, two methods were investigated for the stereoselective introduction of the highly unusual quaternary C-4 center of the A-ring of namenamicin, and the desired stereochemistry was ultimately obtained by way of an intramolecular Michael addition of a xanthate anion derived from the α,β-unsaturated methyl ester.

Iodine, a novel catalyst in carbohydrate reactions I. O-isopropylidination of carbohydrates
TL;DR: Iodine is found to serve as an excellent catalyst in the O-isopropylidination of sugars and sugar alcohols as discussed by the authors, and it has been shown that it can be used as a catalyst for the synthesis of sugar and alcohols.
