Abstract: | reaction: see text] A new method for the synthesis of beta-cyclodextrin-based cluster mannosides by application of the Sonogashira cross-coupling reaction is described. The method allows for the persubstitution of the beta-cyclodextrin at either 2- and 3-positions to give two types of heptavalent clusters, at both 2- and 6-positions to give clusters with 14 mannopyranoside units and at 2-, 3-, and 6-positions to obtain clusters with 21 mannopyranoside ligands. |
