  Synthesis of a chito-tetrasaccharide β-1,4-GlcNAc-β-1,4-GlcN repeating unit

  摘要：

  tert-Butyldimethylsilyl (4-O-acetyl-2-azido-3,6-di-O-benzyl-2-deoxy-beta-D-glucopyranosyl)-(1 -> 4)-3,6-di-O-benzyl-2-deoxy-2-phthalimido-beta-D-glucopyranoside (Kawada and Yoneda [MOCHEM-D-09-00120], 2009), designed as a repeating disaccharide unit in a beta-glucan having two different faces, was converted into a glycosyl donor and an acceptor. The glycosyl acceptor was glycosylated with the donor to afford a chito-tetrasaccharide derivative in good yield. Phthalimido and azido groups in the tetrasaccharide were successively converted into acetamido and free amino groups, and all other protecting groups were cleaved to obtain the chito-tetrasaccharide (2-amino-2-deoxy-beta-D-glucopyranosyl)-(1 -> 4)-(2-acetamido-2-deoxy-beta-D-glucopyranosyl)-(1 -> 4)-(2-amino-2-deoxy-beta-D-glucopyranosyl)-(1 -> 4)-2-acetamido-2-deoxy-D-glucopyranose.
