Add time:09/03/2019    Source:sciencedirect.com

A series of new methyl 6-deoxy-6-[N′-alkyl/aryl-N″-(benzothiazol-2-yl)]guanidino-α-d-glucopyranosides were obtained from the reaction of an alkyl/aryl amine in the presence of HgCl2 and sugar-thiourea derivatives, followed by the removal of protecting groups. The sugar-thiourea derivatives were obtained from the treatment of 2-aminobenzothiazole derivatives with methyl 2,3,4-tri-O-acetyl-6-deoxy-6-isothiocyanato-α-d-glucopyranoside in dry pyridine. Some of the synthesized guanidines displayed anti-influenza activity.
