✦ Synopsis
ABsfracl :
The syntheses of S-a-D-mannosyl-and S-B-D-galactosyl-6~fhio-cyclomaltoheptaoses have been achieved in high yield from 6-deoxy-6-iodn-CD arld activated 1-thiosugars. "Cluster I-thioglycosides" were also obtained by coupling these activated I-thiosugars to 3-bromo-2-(bromomelhyl)-propionic acid and then by attaching these biantennary structures to 6-amino-h-dcoxy-CD through an amide linkage.
