TL;DR: The three disaccharides lactose, cellobiose, and maltose in the form of their acetylated glycosyl bromides have been reacted with 8-ethoxy carbonyloctanol to provide the 1,2-trans-glycosides as mentioned in this paper.

TL;DR: For example, the authors showed that reaction of the same nucleophilic derivatives with 2,3,4-tri-O -acetyl-α- l -fucopyranosyl bromide generally led to corresponding β- l-linked disaccharides.

TL;DR: In this paper, reactions of glycosyl isothiocyanates with diamines such as o-phenylenediamine, 2, 3-diaminopyridine or 5, 6-dimethyluracil gave the corresponding glycoly thioureides in good yields.
Abstract: Reactions of glycosyl isothiocyanates (1a, b, c) with diamines such as o-phenylenediamine, 2, 3-diaminopyridine or 5, 6-diamino-1, 3-dimethyluracil gave the corresponding glycosyl thioureides in good yields. Glycosyl thioureides were converted into N-glycosylaminobenzimidazoles (5a, b, c), N-glycosyl-3-deazapurine (6a) or N-glycosylaminotheophyllines (7a, b, c) in excellent yields through a cyclodesulfurization reaction.
