beta-Selective Glycosidation of a 5-Thioglucosamine Derivative
The first P-selective chemical 5-thioglycosylation of a secondary alcohol was attained with the 2-deoxy-2-phthalimido-5-thioglucose derivative. Requirements of the carbonyl functional groups at C2 to exert anchimeric assistance are discussed on the basis of the results with various functional groups.
