Phosphodiester fragment ManNAc(beta 1-3)GlcNAc(alpha)-P-6ManNAc (beta
1-3)GlcNAc(alpha)Bn of the cell wall polymer of the Actinoplanes sp. I
NA 3697 bacteria was synthesized by the glycosyl H-phosphonate method.
The disaccharide derivatives containing N-acetyl-beta-D-mannosamine,
which are necessary for the condensation, were prepared via beta-gluco
sylation of the corresponding protected derivative of N-acetyl-D-gluco
samine with the subsequent conversion of the disaccharide into 2'-O-tr
ifluoromethane sulfonate, introduction of the azide group with inversi
on at C-2', and reduction.
