Sialic acid is a sugar residue present in many biol. significant glycans of mammals, commonly as a terminal α-glycoside. The chem. structure of sialic acid, which features an anomeric center with carboxyl and methylene substituents, poses a challenge for synthesis of the α-glycoside, thus impeding biol. and therapeutic studies on sialic acid-containing glycans. We present a robust method for the selective α-glycosylation of sialic acid using macro-bicyclized sialic acid donors as synthetic equivalent of structurally constrained oxocarbenium ions to impart stereoselectivity. We demonstrate the power of our method by showcasing broad substrate scope and applicability in the preparation of diverse sialic acid-containing architectures. In addition to this study using 1-Iodopyrrolidine-2,5-dione, there are many other studies that have used 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Product Details of 516-12-1) was used in this study.
1-Iodopyrrolidine-2,5-dione(cas: 516-12-1) is used in the preparation of vinyl sulfones from olefins and benzenesulfinic acid. It acts as a source for I+ and involved in Hunsdiecker reactions for the conversion of cinnamic acids, and propiolic acids to the corresponding alfa-halostyrenes and 1-halo-1-alkynes respectively.
