title: Synthesis of the alpha and beta anomer of an N-triglycosyl dipeptide.
abstract: O-alpha-D-Glucopyranosyl-(1----6)-O-beta-D-glucopyranosyl-(1----6)-1-N- [L-aspart-1-oyl-(L-proline)-4-oyl]-alpha- and -beta-D-glucopyranosylamine have been prepared, as models for a derivative possibly present in the glomerular basement membrane of rats, by condensation of the corresponding D-glucosyl-dipeptide derivatives with 2,3,4,2',3',4',6'-hepta-O-acetyl-alpha-D-isomaltopyranosyl bromide in the presence of mercuric cyanide, followed by deprotection of the trisaccharide-dipeptide derivatives.
