The synthetic strategy involves 1,2-cis-L-glucosylation, one-pot glycosylation, and diastereoselective cyclization, providing the cyclo-oligosaccharides in up to half-gram quantities. See Wu et al.
John Bergeron (McGill, Montreal) described studies showing that exposed hydrophobic residues situated carboxy-terminal to the glucosylation site seem to be part of the recognition code used by the ...
