Abstract
A convenient synthesis of 1′,2,3,3′4,4′-hexa-O-benzylsucrose (4) from the free disaccharide is presented. Diol 4 and previously obtained 1′-O-benzyloxymethyl-2,3,3′,4,4′-penta-O-benzylsucrose (3) served as precursors for chiral crown ether analogs containing a sucrose backbone. Deprotection of macrocyclic compounds (removal of the benzyl blocks) was possible under hydrogenolysis conditions.
