WebGlycal assembly method Definition. Glycal assembly is a novel and efficient manner of synthesizing the oligosaccharides and glycoconjugates (e.g., glycolipids and glycoproteins) to form a stereoselective, high yielding fashion of glycals, glycosidic bonds by both solution- and solid-phase synthesis. In short, it was the glycal mobilization of ... WebFeb 2, 2024 · A highly chemo- and diastereoselective vic-dibromination of olefins has been developed.
